Design and Status of SPIRAL 2 Cryogenic System

Abstract : SPIRAL2 is a rare isotope accelerator witch will based for next years at GANIL laboratory in Caen, France.This machine is dedicated for the production of high intensity radioactive beams (E= 40 Mev, I= 5mA). The driver of SPIRAL2 is a Linac, it uses bulk niobium quarter wave superconducting RF cavities cooled with liquid helium. Mainly, the Linac is composed of two types of cryomodules: 12 CryomoduleA with one cavity and 7 CryomoduleB with two cavities respectively for low and high energy section. The Linac cryogenic transfer line is composed of about 19 valves boxes witch provide to cryomodules two types of helium cryogenic lines: The first at T=4.3K to feed the cavities and the second atT=60K for the thermal shield. There frigerator of this cryogenic installation must evacuate a totat heat loss of about 1kW at T=4.3K and 2.5kW at T=60K. After a short introduction of SPIRAL2 project, the cryogenic installation design will be detailed and its different operation modes will be described. The preliminary cryogenic experimental test results of the first cryomoduleB and A at IPN ORSAY will be also presented and interpreted.
