摘要：

Peking University Superconducting Accelerator Facility (PKU-SCAF) will be constructed as a multi-disciplinary integrated base for fundamental and application researches at Peking University in China since 2004. The main SC accelerator shall produce an electron beam of 20MeV for different kinds of experiments. Electrons from the source are being accelerated by two superconducting resonators, which are TESLA-type 1.3GHz 9-cell superconducting RF cavities operating at 2K and integrated in one cryostat. A superconducting 2.5-cell resonator also working at 2K will serve as capture cavity. Consequently, a cryogenic system with the capacity of about 100W at 2K has to be designed, fabricated, tested and operated for the PKU-SCAF. This paper presents the cryogenic design for PKU-SCAF using computational process analysis software. The cryogenic characteristics of cryomodule, design concept and layout of overall system are discussed. The critical thermal parameters for major components in the superfluid system are given.
