CENBG Control System and Specific Instrumentation Developments for SPIRAL2-DESIR Setups
Résumé
The DESIR facility will be in few years the SPIRAL2 experimental hall at GANIL dedicated to the study of nuclear structure, astrophysics and weak interaction at low energy. Exotic ions produced by the new S3 facility and SPIRAL1 complex will be transferred to high precision experiments in the DESIR building. To guaranty high purity beams to perform high precision measurements on specific nuclei, three main devices are currently being developed at CENBG: a High Resolution Separator (HRS), a General Purpose Ion Buncher (GPIB) and a double Penning Trap named ’PIPERADE’. The Control System (CS) developments we made at CENBG are already used to commission these devices. We present here beamline equipment CS solutions and the global architecture of this SPIRAL2 EPICS based CS.To answer specific needs, instrumental solutions have been developed like PPG used to optimize bunch timing and also used as traps conductor. Recent development using the cost efficient Redpitaya board with an embedded EPICS server will be described. This device used to drive a FCup amplifier and is also used for particle counting and time of flight measurements using our FPGA implementation called ’RedPiTOF’.
