Machine Protection System for the SPIRAL2 Facility

Abstract : The phase 1 of the SPIRAL2 facility, the extension project of the GANIL laboratory, is under construction in Caen, France.The accelerator is based on a linear solution, mainly composed of a normal conducting RFQ and a superconducting linac. One of its specificities is to be designed to accelerate high power deuteron and heavy ion beams from 40 to 200kW, and medium intensity heavy ion beams as well to a few kW. A Machine Protection System, has been studied to control and protect the accelerator from thermal damages for a very large range of beam intensities and powers. This paper presents the technical solutions chosen for this system which is based on two technical subsystems: one dedicated to thermal protection which requires a first PLC associated with a fast electronic system and a second dedicated to enlarged protection which is based on a safety products.
