	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.

The ISAC facility uses the ISOL technique to produce radioactive ions for experiments. The post-accelerator consists of a room temperature linac (ISAC-I) and a su-perconducting linac (ISAC-II). After more than two dec-ades of beam delivery in ISAC, the RF systems have met various challenges regarding increased operation require-ments, system stability issues and performance improve-ments. This paper discusses the detailed challenges in recent years in both ISAC-I and ISAC-II. The upgrade plan or mitigation solution to address each challenge is reported respectively. A hint of the long-term vision at ISAC is also briefly described at the end of the paper.
