TUPHA064	The LIGHT Control and Interlock Systems	ion, controls, interface, timing	543
	R. Moser, H. Pavetits ADAM SA, Geneva, Switzerland
	LIGHT (Linac Image Guided Hadron Technology) is a particle therapy system* developed by Advanced Oncotherapy plc. Accelerator, control and interlock systems are developed by its subsidiary A.D.A.M. SA, a CERN spin-off. The system is being designed to accelerate protons up to 230 MeV using a modular and compact 25-meter-long linear accelerator. It is being designed to operate in pulsed mode where beam properties (energy, pulse charge and spot size) can be changed at 200 Hz. The LIGHT product will be installed in different facilities. As such, the installations will differ in accelerator and beam transfer line layouts, number of treatment rooms (with an optional gantry), facility services, equipment suppliers and equipment versions. Thus the control and interlock systems need to be extensible through configuration and modularization. To achieve this, the control system relies on a multi-tier architecture with a clear separation between front-end devices and controllers. To minimize time-to-market, the systems rely mostly on COTS hardware and software, including a timing and triggering system and a light-weight software framework to standardize front-end controllers. * The LIGHT Proton Therapy System is still subject to conformity assessment by AVO's Notified Body as well as clearance by the USA-FDA

TUPHA102	New Beam Permit Process for the Proton Synchrotron Complex	ion, status, operation, interface	655

	Injecting beams in CERN facilities is subject to the CERN safety rules. It is for this reason that the Beam Permit approval procedure was improved by moving away from a paper-based workflow to a digital form. For each facility the Beam Permits are signed by the various responsible specialists (Access systems, safety equipment, radiation protection, etc…). To achieve this, CERN's official Engineering Data Management System (EDMS) is used. The functionality of EDMS was extended to accommodate the additional requirements, whilst keeping a user friendly web interface. In addition, a new webpage within the CERN OP-webtools site was created with the purpose of providing a visual overview of the Beam Permit status for each facility. This new system is used in the CERN Control Centre (CCC) and it allows the operations team and all people involved in the signature process to follow the Beam Permit status in a more intuitive, efficient and safer way.

THCPA06	A Real-Time Beam Monitoring System for Highly Dynamic Irradiations in Scanned Proton Therapy	ion, radiation, monitoring, real-time	1224

	Funding: This work is supported by the Giuliana and Giorgio Stefanini Foundation. Patient treatments in scanned proton therapy exhibit dead times, e.g. when adjusting beamline settings for a different energy or lateral position. On the one hand, such dead times prolong the overall treatment time, but on the other hand they grant possibilities to (retrospectively) validate that the correct amount of protons has been delivered to the correct position. Efforts in faster beam delivery aim to minimize such dead times, which calls for different means of monitoring irradiation parameters. To address this issue, we report on a real-time beam monitoring system that supervises the proton beam position and current during beam-on, hence while the patient is under irradiation. For this purpose, we sample 1-axis Hall probes placed in beam-scanning magnets and plane-parallel ionization chambers every 10 μs. FPGAs compare sampled signals against verification tables - time vs. position/current charts containing upper and lower tolerances for each signal - and issue interlocks whenever samples fall outside. Furthermore, we show that by implementing real-time beam monitoring in our facility, we are able to respect patient safety margins given by international norms and guidelines.

THCPA07	Development of an Expert System for the High Intensity Neutrino Beam Facility at J-PARC	ion, septum, kicker, experiment	1229
	K. Nakayoshi, Y. Fujii, T. Nakadaira, K. Sakashita KEK, Tsukuba, Japan
	A high intensity neutrino beam produced at J-PARC is utilized by the T2K long baseline neutrino oscillation experiment. To generate the high intensity neutrino beam, a high intensity proton beam is extracted from the 30 GeV Main Ring synchrotron to the neutrino primary beamline. In the beamline, one mistaken shot can potentially do serious damage to beamline equipment. To avoid such a consequence, many beamline equipment interlocks which automatically stop the beam operation are implemented. If an interlock is activated, the beam operator references the operation manual, confirms the safety of the beamline equipment and resumes the beam operation. In order to improve the present system, we are developing an expert system for prompt and efficient understanding of the status of the beamline to quickly resume the beam operation. When an interlock is activated, the expert system references previous interlock patterns and infers what happened in the beamline. And the expert system will suggest how to resume the beam operation to the beam operator. We have developed and evaluated this expert system. In this talk, we will report the development status and initial results.

THPHA098	Development of a PXI Based Test Stand for Automatization of the Quality Assurance of the Patient Safety System in a Proton Therapy Centre	ion, hardware, interface, GUI	1604
	P. Fernandez Carmona, M. Eichin, M. Grossmann, F. Heimann, H.A. Regele, D.C. Weber, R. van der Meer PSI, Villigen PSI, Switzerland
	At the Centre for Proton Therapy at the Paul Scherrer Institute a cyclotron, two gantries and a fixed beamline are being used to treat tumours. In order to prevent non-optimal beam delivery, an interlock patient safety system (PaSS) was implemented that interrupts the treatment if any sub-system reports an error. To ensure correct treatment, the PaSS needs to be thoroughly tested as part of the regular quality assurance as well as after each change. This typically required weeks of work, extensive beam-time and may not comprehensively detect all possible failure modes. With the opportunity of the installation of a new gantry, an automated PaSS test stand was developed that can emulate the rest of the facility. It consists of a NI PXI chassis with virtually unlimited IOs synchronously stimulated or sampled at 1MHz, a set of adapters to connect each type of interfaced signal and a runtime environment. We have also developed a VHDL based formal language to describe stimuli, assertions and specific measurements. We present the use of our test stand in the verification and validation of the PaSS, showing how its full quality assurance, including report generation was reduced to minutes.

THPHA105	ESS Target Safety System Design	ion, target, PLC, controls	1622
	A. Sadeghzadeh, L. Coney, O. Ingemansson, M. Mansouri, M. Olsson ESS, Lund, Sweden
	The purpose of the Target Safety System (TSS) is to protect the public from exposure to unsafe levels of radiation, prevent the release of radioactive material beyond permissible limits, and bring the neutron spallation function into a safe state. In order to fulfill the necessary safety functions, the TSS continually monitors critical parameters within target station systems. If any parameter exceeds an acceptable level, the TSS actuates contactors to cut power to components at the front end of the accelerator and prevent the beam from reaching the target. The TSS is classified as a safety structure, system and component, relevant for the safety of the public and the environment. As such, it requires the highest level of rigor in design and quality for interlock systems at the ESS. Standards are applied to provide a guideline for building the TSS architecture and designing in resistance to single failures and common cause failures. This paper describes the system architecture and design of the TSS, including interfaces with target station and accelerator systems, and explains how the design complies with authority conditions and requirements imposed by development standards.

	Among other functionalities, the tensorics library provides a framework to declaratively describe expressions of arbitrary values and resolve these expressions in different contexts. The Streaming Pool framework provides a comfortable way to transform arbitrary signals from devices into long-living reactive streams. The combination of these two concepts provides a powerful tool to describe modules for online analysis. In this paper we describe this approach, elaborate on the general concepts and give an overview of actual and potential use cases as well as ideas and plans for future evolution.
