Programmable Logic Controller Systems for SPIRAL2
Résumé
PLC provides a large part of the SPIRAL 2 project’s commands. The SPIRAL2 project is based on a multi-beam driver in order to allow both ISOL and low-energy in-flight techniques to produce Radioactive Ion Beams (RIB). A superconducting light/heavy-ion linac with an acceleration potential of about 40 MV capable of accelerating 5 mA deuterons up to 40 MeV and 1 mA heavy ions up to 14.5 MeV/u is used to bombard both thick and thin targets. The PLCs provide vacuum control, access control, part of the machine protection system, control of the cryogenic distribution system, cooling controls, control of RF amplifiers, they are associated with the safety control system. The standards used are presented as well as the general synoptic of the PLC control system. The details of the major systems are presented, the Cryo distribution, the machine protection system, a safety system.
