The SHINE Linac was optimized to accelerate the beam to 8 GeV with 54 high-Q cryomodules (CMs), benefiting from the higher performance of the cavities and CMs. Currently, the mass production of SHINE cavities and CMs is ongoing. Up to now, around 350 high-Q cavities with mid-T baking or N-doping recipes have been fabricated and tested. Most of them have been assembled in CMs. More than 30 CMs have been tested. In this paper, we report the performance of high-Q CMs and lessons learned during the production.
