HLS RF System Improvement 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. The RF system has been improved successfully for HLS storage-ring in NSRL Phase II Project. In this paper, the improvement of the RF transmitter and power transmission system, the development of a new RF cavity and the perfection of RF controls are described in detail. The results and some analyses are presented.
