Description

As national major science and technology infrastructure, Comprehensive Research Facility for Fusion Technology（CRAFT) is being built by ASIPP. Cryogenic system is an important part of the research for superconducting magnets. ASIPP designed and developed a 1KW@4.5K helium cryogenic system to meet some cryogenic testing, such as a conductor performance research platform and a central solenoid model coil test facility. The helium system can provide a cooling capacity more than 1KW, and reserve 3.8K cooling mode. In 2023, the system has been tested successfully, and the performance index of the refrigerator reached the expected requirements. This paper describes the design of CRAFT 1KW @ 4.5K cryogenic system and the results of cooling testing.
