Abstract: A thermodynamic study is performed to identify suitable refrigeration cycles for emerging application to a high-temperature superconductor (HTS) fusion system. According to recent reports on a compact and efficient fusion system, HTS magnets are supposed to operate at about 20 K by forced-flow cooling of helium gas. In addition to the main cryogenic load for the magnets, there are other cooling requirements, including the refrigeration of a thermal shield and current leads. In order to compose a closed refrigeration system without liquid-nitrogen supply or any boil-off loss, modified Brayton cycles are designed to cover the cooling loads with a circulation loop of a coolant for the magnets, the thermal shield, and the current leads. Innovative design is also proposed to integrate the cooling loop with the refrigeration cycle, as helium gas is used as a coolant and a refrigerant.
