Abstract

International audienceThe phase 1 of the SPIRAL2 facility, the extension project of the GANIL laboratory in Caen, France, is to be commissioned. The accelerator, composed of a normal conducting RFQ and a superconducting linac, is designed to accelerate high power deuteron and heavy ion beams up to 200 kW. A Machine Protection System (MPS) has been implemented to protect the accelerator from thermal damages for this very large range of beam intensities. This paper presents the solutions chosen for this system, composed of three subsystems: one dedicated to thermal protection which requires a PLC and a fast electronic system, a second one dedicated to enlarged safety protection, and a third safety subsystem dedicated to fast vacuum valve prot...
