HLS RF cavity development in NSRL phase II project

Hefei light source (HLS) is mainly composed of an 800 MeV electron storage ring and a 200 MeV Linac functioning as its injector. A new RF cavity has been developed successfully for the HLS storage ring in NSRL phase II project. In this paper, the design, fabrication and measurement of the cavity are described in detail. The results and some analyses are presented.
