MOMPL010	Data Streaming With Apache Kafka for CERN Supervision, Control and Data Acquisition System for Radiation and Environmental Protection	controls, SCADA, real-time, monitoring	147
	A. Ledeul, A. Savulescu, G. Segura, B. Styczen CERN, Meyrin, Switzerland
	The CERN HSE - occupational Health & Safety and Environmental protection - Unit develops and operates REMUS - Radiation and Environmental Unified Supervision - , a Radiation and Environmental Supervision, Control and Data Acquisition system, covering CERN accelerators, experiments and their surrounding environment. REMUS is now making use of modern data streaming technologies in order to provide a secure, reliable, scalable and loosely coupled solution for streaming near real-time data in and out of the system. Integrating the open-source streaming platform Apache Kafka allows the system to stream near real-time data to Data Visualization Tools and Web Interfaces. It also permits full-duplex communication with external Control Systems and IIoT - Industrial Internet Of Things - devices, without compromising the security of the system and using a widely adopted technology. This paper describes the architecture of the system put in place, and the numerous applications it opens up for REMUS and Control Systems in general.

	B. Gkotse, G. Pezzullo, F. Ravotti CERN, Meyrin, Switzerland B. Gkotse, P. Jouvelot MINES ParisTech, PSL Research University, Paris, France
	Funding: This project has received funding from the European Union’s Horizon 2020 Research and Innovation program under Grant Agreement no. 654168. The Proton Irradiation Facility (IRRAD) is a reference facility at CERN for characterizing detectors and other accelerator components against radiation. To ensure reliable facility operations and smooth experimental data handling, a new IRRAD Data Manager (IDM) web application has been developed and first used during the last facility run before the CERN Long Shutdown 2. Following best practices in User Experience design, IDM provides a user-friendly interface that allows both users to handle their samples’ data and the facility operators to manage and coordinate the experiments more efficiently. Based on the latest web technologies such as Django, JQuery and Semantic UI, IDM is characterized by its minimalistic design and functional robustness. In this paper, we present the key features of IDM, our design choices and its overall software architecture. Moreover, we discuss scalability and portability opportunities for IDM in order to cope with the requirements of other irradiation facilities.

	F. Horvath, L.J. Fülöp, Sz. Horváth, Z. Héjja, T. Kecskés, I. Kiss, V. Kurusa, G. Kávai, K. Untener ELI-ALPS, Szeged, Hungary
	Funding: ELI-ALPS is supported by the European Union and cofinanced by the European Regional Development Fund (GOP-1.1.1-12/B-2012-000, GINOP-2.3.6-15-2015-00001) ELI-ALPS will be the first large-scale attosecond facility accessible to the international scientific community and its user groups. The facility-wide Personnel Safety System (PSS) has been successfully developed and commissioned for the majority of the laboratories. The system has three major goals. First, it provides safe and automatic sensing and interlocking engineering measures as well as monitoring and controlling interfaces for all laboratories in Building A: emergency stop buttons, interlock and enabling signals, door and roller blind sensors, and entrance control. Second, it integrates and monitors the research technology equipment delivered by external parties as black-box systems (all laser systems, and some others). Third, it includes the PSS subsystems of research technology equipment developed on site by in-house and external experts (some of the secondary sources). The gradual development of the system is based on the relevant standards and best practices of functional safety as well as on an iterative and systematic lifecycle incorporating several internal and external reviews. The system is implemented with an easily maintainable network of safety PLCs.

MOPHA063	Towards a Common Reliability & Availability Information System for Particle Accelerator Facilities	operation, database, medical-accelerators, experiment	356
	K. Höppner, Th. Haberer, K. Pasic, A. Peters HIT, Heidelberg, Germany J. Gutleber, A. Niemi CERN, Meyrin, Switzerland H. Humer AIT, Vienna, Austria
	Funding: This project has received funding from the European Union’s Horizon 2020 Research and Innovation program under grant agreement No 730871. Failure event and maintenance record based data collection systems have a long tradition in industry. Today, the particle accelerator community does not possess a common platform that permits storing and sharing reliability and availability information in an efficient way. In large accelerator facilities used for fundamental physics research, each machine is unique, the scientific culture, work organization, and management structures are often incompatible with a streamlined industrial approach. Other accelerator facilities enter the area of industrial process improvement, like medical accelerators due to legal requirements and constraints. The Heidelberg Ion Beam Therapy Center is building up a system for reliability and availability analysis, exploring the technical and organizational requirements for a community-wide information system on accelerator system and component reliability and availability. This initiative is part of the EU H₂020 project ARIES, started in May 2017. We will present the technical scope of the system that is supposed to access and obtain information specific to reliability statistics in ways not compromising the information suppliers and system producers.

	The detection of beam loss events in accelerators is an important task for machine and personal protection, and for optimization of beam trajectory. An optical beam loss monitor (oBLM) being developed by the Cockcroft Institute at Daresbury Laboratory required integration with the rest of the controls and timing system of the site’s electron accelerator, CLARA (Compact Linear Accelerator for Research and Applications). [1] This paper presents the design and implementation of an inexpensive solution using a Domino Ring Sampling device from PSI. Signals from the oBLM are acquired and can be processed to resolve beam loss events to a resolution of 0.2 m.

MOPHA142	FACET-II Radiation Safety Systems Development	linac, controls, PLC, electron	562
	F. Tao, B.M. Bennett, N. Lipkowitz SLAC, Menlo Park, California, USA
	Facility for Advanced Accelerator Experimental Tests (FACET)-II is an upgrade of the FACET. It uses the middle third of SLAC’s 2-mile long linear accelerator to accelerate the electron beam to 10 GeV, with positron beam to be added in the Stage 2 of the project. Once the project completes in late 2019, it will be operated as a Department of Energy (DOE) user facilities for advanced accelerator science studies. In this paper, we will describe the Radiation Safety Systems (RSS) design and implementation for FACET-II project. RSS include Personnel Protection System (PPS) and Beam Containment System (BCS). Though both systems are safety critical, different technologies are used to implement safety functions. PPS uses Siemens PLC as the backbone for control but legacy CAMAC for data acquisition, while BCS develops customized electronics for faster response to protect safety devices from radiation induced damage.

MOSH1001	Current Status of KURAMA-II	monitoring, network, survey, detector	641
	M. Tanigaki Kyoto University, Research Reactor Institute, Osaka, Japan
	KURAMA-II, a successor of a carborne gamma-ray survey system named KURAMA (Kyoto University RAdiation MApping system), has become one of the major systems for the activities related to the nuclear accident at TEPCO Fukushima Daiichi Nuclear Power Plant in 2011. The development of KURAMA-II is still on the way to extend its application areas beyond specialists. One of such activities is the development of cloud services for serving an easy management environment for data management and interactions with existing radiation monitoring schemes. Another trial is to port the system to a single-board computer for serving KURAMA-II as a tool for the prompt establishment of radiation monitoring in a nuclear accident. In this paper, the current status of KURAMA-II on its developments and applications along with some results from its applications are introduced.

TUAPP03	Low-Cost Modular Platform for Custom Electronics in Radiation-Exposed and Radiation-Free Areas at CERN	controls, FPGA, power-supply, Ethernet	671
	G. Daniluk, C. Gentsos, E. Gousiou, L. Patnaik, M. Rizzi CERN, Geneva, Switzerland
	The CERN control system is comprised of multiple layers of hardware and software. These tiers extend from the hardware deployed close to the machine, up to the software running on computers that operators use for control and monitoring. We are currently developing a new centrally supported service in the layers closest to the accelerator - Distributed I/O and Fieldbus. A key aspect of this project is the selection of industrial standards for the layers, which are currently dominated by custom, in-house designed solutions. Regarding the Distributed I/O layer, this paper describes how we are adapting CompactPCI Serial (CPCI-S) to be suitable as the low-cost modular hardware platform for remote analog and digital I/O applications in radiation-exposed as well as radiation-free areas. We are designing a low cost 3U chassis with a CPCI-S backplane accompanied by a radiation tolerant, switched-mode power supply and an FPGA-based System Board. Regarding the Fieldbus layer, the paper focuses on the radiation-tolerant implementation of the Industrial Ethernet protocol, Powerlink.

TUBPL01	Automatic Web Application Generation From an Irradiation Experiment Data Management Ontology (IEDM)	experiment, interface, operation, data-management	687
	B. Gkotse, F. Ravotti CERN, Meyrin, Switzerland B. Gkotse, P. Jouvelot MINES ParisTech, PSL Research University, Paris, France
	Funding: This project has received funding from the European Union’s Horizon 2020 Research and Innovation program under Grant Agreement no. 654168 Detectors and electronic components in High-Energy Physics experiments are nowadays often exposed to harsh radiation environments. Thus, to insure reliable operation over time, their radiation tolerance must be assessed beforehand through dedicated testing experiments in irradiation facilities. To prevent data loss and perform accurate experiments, these facilities need to rely upon a proper data management system. In prior work, we provided a formal description of the key concepts involved in the data management of irradiation experiments using an ontology (IEDM). In this work, we show how this formalisation effort has a practical by-product via the introduction of an ontology-based methodology for the automatic generation of web applications, using IEDM as a use case. Moreover, we also compare this IEDM-generated web application to the IRRAD Data Manager (IDM), the manually developed web application used for the data handling of the CERN Proton Irradiation facility (IRRAD). Our approach should allow irradiation facility teams to gain access to state-of-the-art data management tools without incurring significant software development effort.

TUBPL03	Experimental Data Transfer System BENTEN at SPring-8	experiment, synchrotron, synchrotron-radiation, operation	702
	T. Matsumoto, Y. Furukawa, Y. Hiraoka, M. Kodera, T. Matsushita, K. Nakada, A. Yamashita, S. Yokota JASRI, Hyogo, Japan
	Recently, there are strong demands on open data to promote data science like material informatics. At SPring-8, we have been operated data transfer system for open data of XAFS measurements since 2013* with the second in the world for amount data*. However, it was difficult to satisfy demands such as generic uses in experimental stations and data federation with other facilities. To overcome these, we newly developed data transfer system BENTEN. BENTEN provides easy-to-use and unified interface with REST API for data access from both inside and outside SPring-8. At SPring-8, proposal number is assigned for each experiment and members in the proposal are defined in DB. BENTEN can also realize restricted data access with the members using authentication and the DB. Data registration was performed with metadata such as experimental conditions and samples. Various metadata in the experiments can be easily defined. To achieve flexible data access with full-text search, we used Elasticsearch as metadata store. We began operation of BENTEN and open access of XAFS data since March this year. We plan to utilize BENTEN to promote open data and data science also with other experimental data. H.

WEPHA096	Timing Signal Distribution for Synchrotron Radiation Experiments Using RF Over White Rabbit	timing, experiment, synchrotron-radiation, synchrotron	1316
	T. Masuda JASRI, Hyogo, Japan
	In synchrotron radiation experiments, some measurements such as nuclear resonant scattering, time-of-flight, and time-resolved measurements necessitate an RF clock and fundamental revolution frequency (zero-address) signals synchronized with a storage ring. Currently, these timing signals are delivered directly over dedicated cables from an accelerator timing station to each experimental station. Considering the upcoming IoT era, it is preferable that these signals can be distributed over a network based on digital technology. Therefore, I am building a proof of concept system (PoCS) that will achieve distributions of the 508.58 MHz clock and the zero-address signals synchronized with the storage ring using RF over White Rabbit. The PoCS consists of a master node, which receives the RF clock and the zero-address signals from the accelerator, and two slave nodes which generate timing signals near experimental stations. Each node employs a SPEC* board and a new FMC DDS**. The slave node will be able to output the RF clock with the arbitrary division rate and phase after reproducing the 508.58 MHz clock. This paper will describe the achieved functions and performance of the PoCS. https://ohwr.org/project/wr-d3s https://ohwr.org/project/spec *https://ohwr.org/project/fmc-dac-600m-12b-1cha-dds

WEPHA127	The IRRAD Proton Irradiation Facility Control, Data Management and Beam Diagnostic Systems: An Outlook of the Major Upgrades Beyond the CERN Long Shutdown 2	proton, controls, experiment, operation	1389
	F. Ravotti, B. Gkotse, M. Glaser, I.M. Mateu, V. Meskova, G. Pezzullo CERN, Geneva, Switzerland B. Gkotse, P. Jouvelot MINES ParisTech, PSL Research University, Paris, France J.M. Sallese EPFL, Lausanne, Switzerland
	Funding: This project has received funding from the European Union’s Horizon 2020 Research and Innovation program under Grant Agreement no. 654168. The IRRAD proton irradiation facility at CERN was built during the Long Shutdown 1 (LS1) to address the irradiation experiment needs of the community working for the High-Luminosity (HL) upgrade of the LHC. The present IRRAD is an upgrade of a historical service at CERN that, since the 90’s, exploits the high-intensity 24 GeV/c PS proton beam for radiation-hardness studies of detector, accelerator and semiconductor components and materials. During its first run (2015-2018), IRRAD provided a key service to the CERN community, with more than 2500 samples irradiated. IRRAD is operated via custom-made irradiation systems, beam diagnostics and data management tools. During the Long Shutdown 2 (LS2), IRRAD will undergo several upgrades in order to cope also with new requirements arising for projects beyond the HL-LHC. In this paper, we (1) describe the various hardware and software equipment developed for IRRAD, and (2) present the main challenges encountered during the first years of operation, which have driven most of the improvements planned for LS2 such as applying machine-learning techniques in the processing and real-time analysis of beam profile data.

Phillips STFC/RAL, Chilton, Didcot, Oxon, United Kingdom E. Stanecka IFJ-PAN, Kraków, Poland
	For the upgrade of the LHC to the High Luminosity LHC the ATLAS detector will install a new all-silicon Inner Tracker (ITk). The innermost part is composed by pixel detectors, the outer part by strip detectors. All together ca. 28000 detector modules will be installed in the ITk volume. Although different technologies were chosen for the inner and outer part, both detectors share a lot of commonalities concerning their requirements. These are operation in the harsh radiation environment, the restricted space for services, and the high power density, which requires a high efficient cooling system. While the sub detectors have chosen different strategies to reduce their powering services, they share the same cooling system, CO₂. The main risks for operation are heat ups and condensation, therefore a common detector control system is under development. It provides a detailed monitoring of the temperature, the radiation and the humidity in the tracker volume. Additionally an interlock system, a hardware based safety system, is designed to protect the sensitive detector elements against upcoming risks. The components of the ITk common monitoring and interlock system are presented.

THCPR07	Electronics for LCLS-II Beam Containment System Loss Monitors	electron, electronics, controls, PLC	1641
	R.A. Kadyrov, C.I. Clarke, A.S. Fisher, M. Petree, C. Yee SLAC, Menlo Park, California, USA
	LCLS-II is a new FEL which is under construction at SLAC National Accelerator Laboratory. Its superconducting electron linac is able to produce up to 1.2 MW of beam power. In event of electron beam loss, radiation levels can exceed allowed levels outside thin shielding originally built for a lower energy LCLS linac. Beam Containment System (BCS) loss monitors are employed to detect the radiation and shut-off the beam within 200 µs, limit the radiation dose in occupied areas and minimize damage to the equipment. sCVD single-crystal diamond particle detectors are used as Point Beam Loss Monitors (PBLM) to detect losses locally. Fiber optics is selected as Long Beam Loss Monitor (LBLM). PMT at downstream end of the LBLM detects light produced by Cherenkov radiation. LBLM provides continuous coverage along electron beam path from the gun to the dump. Unified set of electronics is designed to integrate the charge from PMT or sCVD, compare the loss with predefined threshold and generate the fault if the limit is breached. Continuous self-checking is implemented for both types of sensors. Challenges in electronics design, cable selection and self-checking implementation are discussed.

The CERN HSE - occupational Health & Safety and Environmental protection - Unit develops and operates REMUS - Radiation and Environmental Unified Supervision - , a Radiation and Environmental Supervision, Control and Data Acquisition system, covering CERN accelerators, experiments and their surrounding environment. REMUS is now making use of modern data streaming technologies in order to provide a secure, reliable, scalable and loosely coupled solution for streaming near real-time data in and out of the system. Integrating the open-source streaming platform Apache Kafka allows the system to stream near real-time data to Data Visualization Tools and Web Interfaces. It also permits full-duplex communication with external Control Systems and IIoT - Industrial Internet Of Things - devices, without compromising the security of the system and using a widely adopted technology. This paper describes the architecture of the system put in place, and the numerous applications it opens up for REMUS and Control Systems in general.

The Proton Irradiation Facility (IRRAD) is a reference facility at CERN for characterizing detectors and other accelerator components against radiation. To ensure reliable facility operations and smooth experimental data handling, a new IRRAD Data Manager (IDM) web application has been developed and first used during the last facility run before the CERN Long Shutdown 2. Following best practices in User Experience design, IDM provides a user-friendly interface that allows both users to handle their samples’ data and the facility operators to manage and coordinate the experiments more efficiently. Based on the latest web technologies such as Django, JQuery and Semantic UI, IDM is characterized by its minimalistic design and functional robustness. In this paper, we present the key features of IDM, our design choices and its overall software architecture. Moreover, we discuss scalability and portability opportunities for IDM in order to cope with the requirements of other irradiation facilities.

ELI-ALPS will be the first large-scale attosecond facility accessible to the international scientific community and its user groups. The facility-wide Personnel Safety System (PSS) has been successfully developed and commissioned for the majority of the laboratories. The system has three major goals. First, it provides safe and automatic sensing and interlocking engineering measures as well as monitoring and controlling interfaces for all laboratories in Building A: emergency stop buttons, interlock and enabling signals, door and roller blind sensors, and entrance control. Second, it integrates and monitors the research technology equipment delivered by external parties as black-box systems (all laser systems, and some others). Third, it includes the PSS subsystems of research technology equipment developed on site by in-house and external experts (some of the secondary sources). The gradual development of the system is based on the relevant standards and best practices of functional safety as well as on an iterative and systematic lifecycle incorporating several internal and external reviews. The system is implemented with an easily maintainable network of safety PLCs.

Failure event and maintenance record based data collection systems have a long tradition in industry. Today, the particle accelerator community does not possess a common platform that permits storing and sharing reliability and availability information in an efficient way. In large accelerator facilities used for fundamental physics research, each machine is unique, the scientific culture, work organization, and management structures are often incompatible with a streamlined industrial approach. Other accelerator facilities enter the area of industrial process improvement, like medical accelerators due to legal requirements and constraints. The Heidelberg Ion Beam Therapy Center is building up a system for reliability and availability analysis, exploring the technical and organizational requirements for a community-wide information system on accelerator system and component reliability and availability. This initiative is part of the EU H₂020 project ARIES, started in May 2017. We will present the technical scope of the system that is supposed to access and obtain information specific to reliability statistics in ways not compromising the information suppliers and system producers.

The detection of beam loss events in accelerators is an important task for machine and personal protection, and for optimization of beam trajectory. An optical beam loss monitor (oBLM) being developed by the Cockcroft Institute at Daresbury Laboratory required integration with the rest of the controls and timing system of the site’s electron accelerator, CLARA (Compact Linear Accelerator for Research and Applications). [1] This paper presents the design and implementation of an inexpensive solution using a Domino Ring Sampling device from PSI. Signals from the oBLM are acquired and can be processed to resolve beam loss events to a resolution of 0.2 m.

Facility for Advanced Accelerator Experimental Tests (FACET)-II is an upgrade of the FACET. It uses the middle third of SLAC’s 2-mile long linear accelerator to accelerate the electron beam to 10 GeV, with positron beam to be added in the Stage 2 of the project. Once the project completes in late 2019, it will be operated as a Department of Energy (DOE) user facilities for advanced accelerator science studies. In this paper, we will describe the Radiation Safety Systems (RSS) design and implementation for FACET-II project. RSS include Personnel Protection System (PPS) and Beam Containment System (BCS). Though both systems are safety critical, different technologies are used to implement safety functions. PPS uses Siemens PLC as the backbone for control but legacy CAMAC for data acquisition, while BCS develops customized electronics for faster response to protect safety devices from radiation induced damage.

KURAMA-II, a successor of a carborne gamma-ray survey system named KURAMA (Kyoto University RAdiation MApping system), has become one of the major systems for the activities related to the nuclear accident at TEPCO Fukushima Daiichi Nuclear Power Plant in 2011. The development of KURAMA-II is still on the way to extend its application areas beyond specialists. One of such activities is the development of cloud services for serving an easy management environment for data management and interactions with existing radiation monitoring schemes. Another trial is to port the system to a single-board computer for serving KURAMA-II as a tool for the prompt establishment of radiation monitoring in a nuclear accident. In this paper, the current status of KURAMA-II on its developments and applications along with some results from its applications are introduced.

The CERN control system is comprised of multiple layers of hardware and software. These tiers extend from the hardware deployed close to the machine, up to the software running on computers that operators use for control and monitoring. We are currently developing a new centrally supported service in the layers closest to the accelerator - Distributed I/O and Fieldbus. A key aspect of this project is the selection of industrial standards for the layers, which are currently dominated by custom, in-house designed solutions. Regarding the Distributed I/O layer, this paper describes how we are adapting CompactPCI Serial (CPCI-S) to be suitable as the low-cost modular hardware platform for remote analog and digital I/O applications in radiation-exposed as well as radiation-free areas. We are designing a low cost 3U chassis with a CPCI-S backplane accompanied by a radiation tolerant, switched-mode power supply and an FPGA-based System Board. Regarding the Fieldbus layer, the paper focuses on the radiation-tolerant implementation of the Industrial Ethernet protocol, Powerlink.

Detectors and electronic components in High-Energy Physics experiments are nowadays often exposed to harsh radiation environments. Thus, to insure reliable operation over time, their radiation tolerance must be assessed beforehand through dedicated testing experiments in irradiation facilities. To prevent data loss and perform accurate experiments, these facilities need to rely upon a proper data management system. In prior work, we provided a formal description of the key concepts involved in the data management of irradiation experiments using an ontology (IEDM)*. In this work, we show how this formalisation effort has a practical by-product via the introduction of an ontology-based methodology for the automatic generation of web applications, using IEDM as a use case. Moreover, we also compare this IEDM-generated web application to the IRRAD Data Manager (IDM), the manually developed web application used for the data handling of the CERN Proton Irradiation facility (IRRAD). Our approach should allow irradiation facility teams to gain access to state-of-the-art data management tools without incurring significant software development effort.

Recently, there are strong demands on open data to promote data science like material informatics. At SPring-8, we have been operated data transfer system for open data of XAFS measurements since 2013* with the second in the world for amount data**. However, it was difficult to satisfy demands such as generic uses in experimental stations and data federation with other facilities. To overcome these, we newly developed data transfer system BENTEN. BENTEN provides easy-to-use and unified interface with REST API for data access from both inside and outside SPring-8. At SPring-8, proposal number is assigned for each experiment and members in the proposal are defined in DB. BENTEN can also realize restricted data access with the members using authentication and the DB. Data registration was performed with metadata such as experimental conditions and samples. Various metadata in the experiments can be easily defined. To achieve flexible data access with full-text search, we used Elasticsearch as metadata store. We began operation of BENTEN and open access of XAFS data since March this year. We plan to utilize BENTEN to promote open data and data science also with other experimental data.

Timing Signal Distribution for Synchrotron Radiation Experiments Using RF Over White Rabbit

T. Masuda
JASRI, Hyogo, Japan

In synchrotron radiation experiments, some measurements such as nuclear resonant scattering, time-of-flight, and time-resolved measurements necessitate an RF clock and fundamental revolution frequency (zero-address) signals synchronized with a storage ring. Currently, these timing signals are delivered directly over dedicated cables from an accelerator timing station to each experimental station. Considering the upcoming IoT era, it is preferable that these signals can be distributed over a network based on digital technology. Therefore, I am building a proof of concept system (PoCS) that will achieve distributions of the 508.58 MHz clock and the zero-address signals synchronized with the storage ring using RF over White Rabbit*. The PoCS consists of a master node, which receives the RF clock and the zero-address signals from the accelerator, and two slave nodes which generate timing signals near experimental stations. Each node employs a SPEC** board and a new FMC DDS***. The slave node will be able to output the RF clock with the arbitrary division rate and phase after reproducing the 508.58 MHz clock. This paper will describe the achieved functions and performance of the PoCS.

Funding: This project has received funding from the European Union’s Horizon 2020 Research and Innovation program under Grant Agreement no. 654168.
The IRRAD proton irradiation facility at CERN was built during the Long Shutdown 1 (LS1) to address the irradiation experiment needs of the community working for the High-Luminosity (HL) upgrade of the LHC. The present IRRAD is an upgrade of a historical service at CERN that, since the 90’s, exploits the high-intensity 24 GeV/c PS proton beam for radiation-hardness studies of detector, accelerator and semiconductor components and materials. During its first run (2015-2018), IRRAD provided a key service to the CERN community, with more than 2500 samples irradiated. IRRAD is operated via custom-made irradiation systems, beam diagnostics and data management tools. During the Long Shutdown 2 (LS2), IRRAD will undergo several upgrades in order to cope also with new requirements arising for projects beyond the HL-LHC. In this paper, we (1) describe the various hardware and software equipment developed for IRRAD, and (2) present the main challenges encountered during the first years of operation, which have driven most of the improvements planned for LS2 such as applying machine-learning techniques in the processing and real-time analysis of beam profile data.

For the upgrade of the LHC to the High Luminosity LHC the ATLAS detector will install a new all-silicon Inner Tracker (ITk). The innermost part is composed by pixel detectors, the outer part by strip detectors. All together ca. 28000 detector modules will be installed in the ITk volume. Although different technologies were chosen for the inner and outer part, both detectors share a lot of commonalities concerning their requirements. These are operation in the harsh radiation environment, the restricted space for services, and the high power density, which requires a high efficient cooling system. While the sub detectors have chosen different strategies to reduce their powering services, they share the same cooling system, CO₂. The main risks for operation are heat ups and condensation, therefore a common detector control system is under development. It provides a detailed monitoring of the temperature, the radiation and the humidity in the tracker volume. Additionally an interlock system, a hardware based safety system, is designed to protect the sensitive detector elements against upcoming risks. The components of the ITk common monitoring and interlock system are presented.

SLAC, Menlo Park, California, USA

LCLS-II is a new FEL which is under construction at SLAC National Accelerator Laboratory. Its superconducting electron linac is able to produce up to 1.2 MW of beam power. In event of electron beam loss, radiation levels can exceed allowed levels outside thin shielding originally built for a lower energy LCLS linac. Beam Containment System (BCS) loss monitors are employed to detect the radiation and shut-off the beam within 200 µs, limit the radiation dose in occupied areas and minimize damage to the equipment. sCVD single-crystal diamond particle detectors are used as Point Beam Loss Monitors (PBLM) to detect losses locally. Fiber optics is selected as Long Beam Loss Monitor (LBLM). PMT at downstream end of the LBLM detects light produced by Cherenkov radiation. LBLM provides continuous coverage along electron beam path from the gun to the dump. Unified set of electronics is designed to integrate the charge from PMT or sCVD, compare the loss with predefined threshold and generate the fault if the limit is breached. Continuous self-checking is implemented for both types of sensors. Challenges in electronics design, cable selection and self-checking implementation are discussed.
