MOMPR008	SharePoint for HEPS Technical Systems and Project Management	project-management, database, MMI, interface	175
	X.H. Wu, L. Bai, C.P. Chu IHEP, Beijing, People’s Republic of China
	High Energy Photon Source is the latest planned synchrotron light source in China which is designed for ultra-low emittance and high brightness. The accelerator and beamlines contains tens of thousands of devices which require systematic management. It is also necessary to capture project management information systematically. HEPS chooses the Microsoft SharePoint as the document tool for the project and all technical systems. Additionally, Microsoft Project Server on top of SharePoint is used for the project management. Utilizing the SharePoint and Project software can facilitate a lot of daily work for the HEPS project. This paper describes the SharePoint and Project setup and various applications been developed so far.

MOPHA058	Lua-Language-Based Data Acquisition Processing EPICS Subscription Filters	EPICS, timing, factory, data-acquisition	342
	J.O. Hill LANL, Los Alamos, New Mexico, USA
	Funding: Work supported by US Department of Energy under contract DE-AC52-06NA25396. A previous paper described an upgrade to EPICS enabling client side tools at LANSCE to receive subscription updates filtered selectively to match a logical configuration of LANSCE beam gates, as specified dynamically by control room application programs. This update paper will examine evolving enhancements enabling Lua-language based data acquisition processing subscription update filters, specified by snippets of Lua-language source-code embedded within the EPICS channel-name’s postfix. We will discuss the generalized utility of this approach across a wide range of data acquisition applications, projects, and platforms; the performance and robustness of our production implementation; and our operational experience with the software at LANSCE.

MOPHA078	Renovation of the SPS Personnel Protection System: A Configurable Approach	controls, software, PLC, operation	395
	T. Ladzinski, B. Fernández Adiego, F. Havart CERN, Meyrin, Switzerland
	The renovation of the SPS Personnel Protection System (PPS) comprises the installation of industrial access control solutions and the implementation of a new safety instrumented system tailored to the particular needs of the accelerator. The SPS has been a working horse of the CERN accelerator complex for many decades and its configuration has changed through the many years of operation. The classic solutions for safety systems design, used in the LHC and PS machines, have not been judged adequate for this accelerator undergoing perpetual changes, composed of many sites forming several safety chains. In order to avoid expensive software modifications, each time the accelerator configuration evolves, a configurable safety software design was proposed. This paper presents the hardware architecture of the PLC-based SPS PPS and the configurable software architecture proposed. It further reports on the testing and formal verification activities performed to validate the safety software and discusses the pros and cons of the configurable approach.

	Funding: U.S. Department of Energy Office of Science, under Contract No. DE-AC02-06CH11357 The integration of structured data and the PV Access network protocol into the EPICS toolkit has opened up many possibilities for added functionality and features, which more and more facilities are looking to leverage. At the same time however the core developers also have to cope with technical debt incurred in the race to deliver working software. This paper will describe the current status of EPICS 7, and some of the work done in the last two years following the reorganization of the code-base. It will cover some of the development group’s technical and process changes, and echo questions being asked about support for recent language standards that may affect support for older target platforms, and adoption of other internal standards for coding and documentation.

	The Cherenkov Telescope Array (CTA) project is the initiative to build the next-generation gamma-ray observatory. With more than 100 telescopes planned to be deployed in two sites, CTA is one of the largest astronomical facilities under construction. The Array Control and Data Acquisition (ACADA) system will be the central element of on-site CTA Observatory operations. The mission of the ACADA system is to manage and optimize the telescope array operations at each of the CTA sites. To that end, ACADA will provide all necessary means for the efficient execution of observations, and for the handling of the several Gb/s generated by each individual CTA telescope. The ACADA system will contain a real-time analysis pipeline, dedicated to the automatic generation of science alert candidates based on the inspection of data being acquired. These science alerts, together with external alerts arriving from other scientific installations, will permit ACADA to modify ongoing observations at sub-minute timescales in order to study high-impact scientific transient phenomena. This contribution describes the challenges, architecture, design principles, and development status of the ACADA system.

	Funding: This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No 730872 As more and more scientific data are stored at photon sources there is a growing need to provide services to access to view, reduce and analyze the data remotely. The Calipsoplus* project, in which all photon sources in Europe are involved in, has recognized this need and created a prototype portal for Data Analysis as a Service. This paper will present the technology choices, the architecture of the blueprint, the prototype services and the objectives of the production version planned in the medium term. The paper will cover the challenges of building a portal from scratch which covers the needs of multiple sites, each with their own data catalogue, local computing infrastructure and different workflows.

	Phoebus is a Java/JavaFX framework for creating state-of-the-art, next-generation desktop applications for monitoring and controlling EPICS systems. The recent developments in Java and JavaFX have made it possible to reconsider the role of the Eclipse Rich Client Platform (RCP) in the development of client applications. Phoebus’s aim is to provide a simple to use and yet "rich-enough" application framework to develop modular JavaFX desktop applications for the most recent Java platform. Phoebus is an extensible framework for multiple control system protocols. It provides features for developing robust and scalable multi-threaded client applications. Key features include event rate decoupling, caching and queuing, and a common set of immutable data types to represent controls data from various protocols. The paper describes the framework as used to implement applications and service for monitoring EPICS PVs. The benefits highlighted will provide the EPICS community a new development perspective.
