The SHINE project requires more than six hundred 1.3GHz cavities and sixteen 3.9GHz cavities for the superconducting accelerator. These cavities are from both domestic and foreign companies. The cavities fabricated in domestic companies requires correspond-ing capacity of surface-treatment. For the R&D of surface-treatment technology and mass production of SRF cavities, we have been constructing a new surface-treatment platform near Shanghai for SHINE project. In this paper, we report the design, construction, commissioning and operation of this platform.

SHINE project requires about 75 cryomodules with superconducting radio-frequency cavities to accelerate the beam to 8 GeV. Key components, technologies of cryomodule have been developing through prototypes and pre-series cryomodules. Up to now, several sets of cryomodule with high-Q cavities have been assembled and tested. We present the development status of SHINE cryomodules, including prototype cryomodules and the first ones for project.
