SESAME is a synchrotron light source under installation located in Allan, Jordan. It consists of 2.5 GeV storage-ring, a 800 MeV Booster-Synchrotron and a 22 MeV Microtron as Pre-Injector. SESAME succeeded to get the first beam from Microtron, the booster is expected to be commissioned by the end of 2013, the storage-ring by the end of 2015 and the first beam-lines in 2016. This paper presents building of control systems of SEAME booster. EPICS is the main control-software tool and EDM for building GUIs which is being replaced by CSS. PLCs are used mainly for the interlocks in the vacuum system and power-supplies of the magnets, and in diagnostics for florescent screens and camera- switches. Soft IOCs are used for different serial devices (e.g. vacuum gauge controllers) through Moxa terminal servers and Booster power supplies through Ethernet connection. Libera Electron modules with EPICS tools (IOCs and GUIs) from Diamond Light Source are used for beam position monitoring. The timing System consists of one EVG and three EVR cards from Micro Research Finland (MRF). A distributed version control repository using Git is used at SESAME to track development of the control subsystems.
A Hazard Driven Approach to Accelerator Safety System Design - How CLS Successfully Applied ALARP in the Design of Safety Systems
Elder Matias (Mighty Oaks, Victoria, British Columbia), Mohamed Benmerrouche, Grant Cubbon, Allen Hodges, Hao Zhang (CLS, Saskatoon, Saskatchewan)
All large scale particle accelerator facilities end up utilising computerised safety systems for the accelerator access control and interlock system including search lockup sequences and other safety functions. Increasingly there has been a strong move toward IEC 61508 based standards in the design of these systems. CLS designed and deployed its first IEC 61508 based system nearly 10 years ago. The challenge has increasingly been to manage the complexity of requirements and ensure that features being added into such systems were truly requirements to achieve safety. Over the past few years CLS has moved to a more structured Hazard Analysis technique that is tightly coupled and traceable through the design and verification of its engineered safety systems. This paper presents the CLS approach and lessons learned.
Recent Changes to Beamline Software at the Canadian Light Source

The Canadian Light Source has ongoing work to improve the user interfaces at the beamlines. Much of the direction has made use of Qt and EPICS, using both C++ and Python in providing applications. Continuing work on the underlying data acquisition and visualization tools provides a commonality for both development and operation, and provisions for extending tools allow flexibility in types of experiments being run.
A Rational Approach to Control System Development Projects That Incorporates Risk Management
Elder Matias (CLS, Saskatoon Saskatchewan; Mighty Oaks, Victoria, British Columbia)
Over the past year CLS has migrated towards a project management approach based on the Project Management Institute (PMI) guidelines as well as adopting an Enterprise Risk Management (ERM) program. Though these are broader organisational initiatives they do impact how controls systems and data acquisition software activities and planned, executed and integrated into larger scale projects. Synchrotron beamline development and accelerator upgrade projects have their own special considerations that require adaptation of the more standard techniques that are used. Our ERM processes integrate in two ways: (1) in helping to identify and prioritising those projects that we should be undertaking and (2) in helping identify risks that are internal to the project. These broader programs are resulting in us revising and improving processes we have in place for control and data acquisition system development and maintenance. This paper examines the approach we have adopted, our preliminary experience and our plans going forward.
Achieving a Successful Alarm Management Deployment - The CLS Experience
Elder Matias (Mighty Oaks, Victoria, British Columbia), Laurier Baribeau (McGill, Montreal, Quebec), Tonia Batten, Jianwei Li, Ward A Wurtz (CLS, Saskatoon, Saskatchewan)
Alarm management systems promise to improve situational awareness, aid operational staff in correcting responding to accelerator problems and reduce downtime. Many facilities, including the Canadian Light Source (CLS), have been challenged in achieving this goal. At CLS past attempts focusing on software features and capabilities. Our third attempt switched gears and instead focused on human factors engineering techniques and the associated response processes to the alarm. Aspects of ISA 18,2, EEMUA 191 and NREG-700 standards were used. CLS adopted the CSS BEAST alarm handler software. Work was also undertaken to identify bad actors and analyzing alarm system performance and to avoid alarm flooding. The BEAST deployment was augmented with a locally developed voice annunciation system for a small number of critical high impact alarms and auto diallers for shutdown periods when the control room is not staffed. This paper summaries our approach and lessons learned.
