Development of the Thermal Beam Loss Monitors of the SPIRAL2 Control System

Abstract : The Spiral2 linear accelerator will drive high intensity beams, up to 5mA, to up to 200kW at linac exit. Such beams can seriously damage and activate the machine ! To prevent from such situation, the Machine Protection System (MPS) has been designed. This system is connected to diagnostics indicating if the beam remains under specific limits. As soon as a diagnostic detects its limit is crossed, it informs the MPS which will in turn take actions that can lead to a beam cut-off in appropriated timing requirements. In this process, the Beam Loss Monitors (BLM) are involved in monitoring prompt radiation generated by beam particles interactions with beam line components and responsible for activation, on one side, and thermal effects, on the other side. BLM system relies mainly on scintillator detectors, NIM electronics and a VME subsystem monitoring the heating of the machine. This subsystem, also called "Thermal BLM", will be integrated in the Spiral2 EPICS environment. For its development, a specific project organization has been setup since the development is subcontracted to Cosylab. This paper focuses on the Thermal BLM controls aspects and describes this development process.
