Abstract

Due to the exponential dependence of the BCS (Bardeen, Cooper and Schriffer) surface resistance with temperature, reducing the operating temperature of SRF cavity will result in lower radio-frequency loss for the cavity, but the efficiency of the cryogenic plant reduces drastically too. The saturated super-fluid helium cooling cycles and operation temperature for a 1.3 GHz superconducting resonance frequency cavity system were analyzed in terms of improving the refrigeration efficiency of SRF cooling system and lowering the cavity dynamic loss. The optimized operation temperature for the 1.3 GHz SRF cavity systems for PKU-SCAF (Peking University-Superconducting Accelerator Facilities) is around 1.95 K. The suitable cooling cycle is proposed finally.
