Tests status of the SPIRAL 2 low beta cryomodules

TU5PFP041International audienceThe Spiral 2 project at GANIL aims at producing exoticion beams for Nuclear Physics. The accelerator of theprimary beam is a superconducting Linac designed toprovide 5 mA deuteron beams at 40 MeV. It will alsoallow accelerating stable ions of different Q/A valuesranging from protons to Q/A=1/6 heavy ions. Theaccelerator should be commissioned by the end of 2011,first beam in 2012. The first tests aiming to produceexotic beams are planned one year later.The superconducting LINAC consists of 12 low beta(0.07) quarter wave (88 MHz) superconducting (SC)cavities and 24 beta (0.14) SC cavities integrated in theircryomodule.The status of the low beta cryomodules, supplied by theIrfu institute of CEA Saclay, is reported in this paper. TheRF full power tests were performed on the qualifyingcryomodule at the end of 2008 and the beginning of 2009,and the tests of the first series cavity in vertical cryostatare in cours
