Four cryomodules with 166.6 MHz β=1 QWR cavities are proposed for HEPS, while each cavity will providing 1.2 MV and 145 kW to the electron beam. The vertical and horizotal tests of the proof-of-principle cavities were recently conducted. 650 MHz 2-cell cavities and 1.3 GHz 9-cell cavities were proposed for the CEPC, and high Q technology is adopted by the project. Infrastructures are developed for the high Q study, while R&D on single-cell cavities are under-way. Efforts on learning mass-production of cavities and cavity-string were also made for both CEPC and SHINE projects. SRF linac from 80 MeV to over 300 MeV were adopted for the upgrade of CSNS, with 325 MHz Double-spoke cavities at β=0.50 and 650 MHz-5cell elliptical cavities at β=0.65. The PAPS SRF facility is biased on mass production for large SRF projects, i.e. aiming at assembly and testing of 200-400 cavities & couplers and 20 cryomodules per year. The equipment installation and commissioning is on going. The activities and progress of these SRF projects with be addressed in this presentation. PB - JACoW Publishing CP - Geneva, Switzerland ER -
