Tests of the low beta cavities and cryomodules for the SPIRAL 2 Linac

TUPPO003https://accelconf.web.cern.ch/SRF2009/index.htmInternational audienceThe IRFU institute of CEA Saclay is in charge of the 12low beta cryomodules that will be installed on the firstsection of the SPIRAL 2 superconducting LINAC. Eachcryomodule houses a single QWR cavity at 88MHz andE=0.07 cooled with liquid helium at 4.4 K. Allcomponents of the cryomodules are manufactured by theindustry. The power coupler is provided by LPSCGrenoble. The assembling and tests are performed by theCEA.The RF power tests (P max = 10 kW) were performed onthe qualifying cryomodule at the end of 2008 beforelaunching the order of the 11 serial cryomodules. The twofirst cavities of the series were tested in vertical cryostatbefore the summer 2009. A summary of these tests andthe present status of this project are reporte
