TI - Commissioning of the VECC Cryomodule J2 - Proc. of LINAC2022, Liverpool, UK, 28 August-02 September 2022 CY - Liverpool, UK T2 - International Linear Accelerator Conference T3 - 31 LA - english AB - A quarter-wave resonator (QWR) cryomodule was designed and assembled at TRIUMF for the energy upgrade of the VECC ISOL-RIB facility to boost radioactive isotopes from 1MeV/u to 2MeV/u. The top loading cryomodule was chosen based on the ISAC-II low energy section design, consisting of four superconducting QWRs and one superconducting solenoid. The major change from ISAC-II concept is separating the RF space vacuum from the isolation vacuum. The cryogenic commissioning was recently completed. The cold mass alignments and the cryogenic heat loads were measured. The cavity performance was qualified in both test regime and operating regime. The cavity degradations caused by magnetic pollution from solenoid and the recovery procedure were verified. This paper will report the detailed results of the commissioning.
