Abstract
A high field superconducting magnet with a 100 mm room-temperature bore is being designed and installed in the High Magnetic Field Laboratory in China. To provide an optional cryogenic supply plan for a compact CICC coil in this superconducting magnet, a forced-flow-cooling system based on the GM/JT cycle is designed. In this paper, the design of the cryogenic system is briefly described. Meanwhile, the influence of stage temperature of GM cryocooler and helium gas inlet pressure on the performance of the system is thermodynamically analyzed. The results of the analysis make it clear that, the temperature of GM cryocooler precooling stage plays a very important role on the system performance. And different operational helium gas inlet pressure and its thermal characteristics in the cooling system are also discussed. Based on these studies, the forced-flow-cooling system for the CICC coil can be optimized and we can get a good reference for choosing GM cryocoolers.
