Similation developments for Spoke superconducting cavities design

In the frame of the HIPPI JRA, which proposed R&D activities meant to foster the development of a common European technology base for the construction of high intensity pulsed linear accelerator, IPN Orsay is involved in the development of the Spoke type superconducting cavities. The 352 MHz 2 gaps Spoke cavity has been proposed by IPN Orsay for beta 0.15 sections, and the 352 MHz 4 gaps Spoke cavity has been proposed by FJZ Jülich for beta 0.65 sections. The important simulation investigations have been realized at IPN Orsay, as the numerical codes adapted for superconducting cavity electromagnetic and mechanical behaviors' studies are different from FJZ laboratory, the simulation results supply confirmations about 4 gaps Spoke design made by FJZ Jülich

Performance improvement of the multicell cavity prototype for proton Linac projects

The CEA-Saclay / IPN-Orsay collaboration allowed to manufacture a multicell superconducting RF cavity prototype for proton linac. Since the first experimental results [1], obtained in a vertical cryostat and the horizontal cryostat CryHoLab, the accelerating field Eacc has been recently increased up to 19 MV/m with a quality factor Q0 = 9.109 and a limitation by quench. However some improvements are still needed, in particular to suppress the field emission above 16 MV/m
