Status of the SPIRAL 2 Superconducting LINAC
Résumé
SPIRAL2 is a radioactive beams facility, composed of a superconducting linac driver, delivering deuterons with an energy up to 40 MeV (5 mA) and heavy ions with an energy of 14.5 MeV/u (1 mA). The superconducting linac is composed of two families of quarter wave resonators: type A (optimized for ¯=0.07, 1 per cryomodule) and B (¯=0.12, 2 per cryomodule). The accelerator is scheduled to be commissionned from mid-2011 onwards. The project is therefore in production phase. This paper summarizes the latest results and the status of the superconducting linac. All 16 type B cavities have been tested. Cryomodules from both families are presently beeing assembled in series. Installation in the new building shall begin inMay 2011.
