Description

Recently, the SHINE Linac layout has been modified to use fewer cryomodules (CMs) to reach 8 GeV, bene-fiting from the higher performance of high-Q cavities and CMs. The mass production of SHINE cavities and CMs is currently underway. To date, more than 100 mid-T baked cavities and 100 N-doped cavities have been vertically tested. Most of them have been assem-bled into cryomodules, achieving high Q and quite high gradient in horizontal test. These high-Q CMs are being gradually installed into the Linac section. Two 3.9 GHz CMs have been assembled and tested, demonstrating excellent RF performance. This paper will report the progress in the production and performance of the cavities and CMs.
