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.

Evolution of Control System Standards on the Diamond Synchrotron Light Source

Control system standards for the Diamond synchrotron light source were initially developed in 2003. They were largely based on Linux, EPICS and VME and were applied fairly consistently across the three accelerators and first twenty photon beamlines. With funding for further photon beamlines in 2011 the opportunity was taken to redefine the standards to be largely based on Linux, EPICS, PC’s and Ethernet. The developments associated with this will be presented, together with solutions being developed for requirements that fall outside the standards.

Fast Orbit Feedback Control in Mode Space

This paper describes the design and implementation of fast orbit feedback control in mode space. Using a Singular Value Decomposition (SVD) of the response matrix, each singular value can be associated with a spatial mode and enhanced feedback performance can be achieved by applying different controller dynamics to each spatial mode. By considering the disturbance spectrum across both dynamic and spatial frequencies, controller dynamics for each mode can be selected. Most orbit feedback systems apply only different gains to each mode however; mode space control gives greater flexibility in control design and can lead to enhanced disturbance suppression. Mode space control was implemented on the Booster synchrotron at Diamond Light Source, operated in stored beam mode. Implementation and performance of the mode space controller are presented.
