  For many years our Institute CEA IRFU has had a sound experience in VME and EPICS. For the accelerator projects SPIRAL2 at Ganil in Normandy and IFMIF/LIPAc at JAEA/Rokkasho (Japan) the EPICS control systems were based on VME. For 5 years our Institute has been involved in several in-kind collaboration contracts with ESS. For the first contracts (ESS test stands, Source and LEBT controls) ESS recommended us to use VME based solutions on IOxOS boards. Our close collaboration with ESS, their support and the requirements for new projects have led us to develop a standardized hardware and software platform called IRFU EPICS Environment based on microTCA.4 and MRF timing system. This paper describes the advantages of the combination of these recent technologies and the local control system architectures in progress for the SARAF project.

  The beam loss detection is of the utmost importance for accelerator safety. At CEA, we are closely collaborating with ESS and DMCS on development of ESS nBLM. The system is based on Micromegas* gaseous detector sensitives to fast neutrons produced when beam particles hit the accelerator materials. This detector has powerful features: reliable neutron detection and fast time response. The nBLM control system provides slow monitoring, fast security based on neutron counting and post mortem data. It is fully handled by EPICS, which drives 3 different subsystems: a Siemens PLC regulates the gas line, a CAEN crate controls low and high voltages, and a MTCA system based on IOxOS boards is in charge of the fast data processing for 16 detectors. The detector signal is digitized by the 250 Ms/s ADC, which is further processed by the firmware developed by DMCS and finally retrieved and sent to EPICS network. For other accelerator projects, we are designing nBLM system close to ESS nBLM one. In order to be able to sustain the full control system, we are developing the firmware and the driver. This paper summarizes CEA’s work on the nBLM control system for the ESS and other accelerators.
