Development of a beta 0.12, 88 MHz, quarter-wave resonator and its cryomodule for the SPIRAL2 project

Abstract : SPIRAL2 is a radioactive beams facility, composed of a superconducting linac driver, delivering deuterons with an energy of up to 40 MeV (5 mA) and heavy ions with an energy of 14.5 MeV/u (1 mA). This facility is now fully approved by the French government. The first prototype of beta 0.12 quarter-wave resonator has been recently fabricated by Zanon company and tested at IPN Orsay. The details on its fabrication and the results of the RF and mechanical tests at 4 K will be presented. Then, we will show the design of the cryomodule-B, dedicated to the high energy section of the linac, which is now ready to be ordered. Finally, the last studies of the R&D program, such as the last optimizations of the geometry, the new developments of the tuning system and the design of the helium vessel, are described.
