Abstract
Provided are a cryogen recondensing system and a superconducting magnet apparatus including the same. The cryogen recondensing system includes a primary reservoir that stores cryogen for cooling a superconducting coil; a refrigerator that recondenses gas cryogen of cryogen stored in the primary reservoir; a secondary reservoir that stores gas cryogen; and a secondary reservoir tube that connects the primary reservoir to the secondary reservoir, through which the gas cryogen flows.
Claims19
A cryogen recondensing system comprising:
- a primary reservoir configured to store cryogen for cooling a superconducting coil;
- a heat shield portion configured to thermally shield the superconducting coil from external conditions;
- a first refrigerator configured to cool the heat shield portion at a first temperature;
- a second refrigerator configured to recondense gas cryogen of cryogen stored in the primary reservoir at a second temperature, the second temperature being lower than the first temperature;
- a secondary reservoir configured to store gas cryogen;
- and
- a secondary reservoir tube configured to connect the primary reservoir to the secondary reservoir, and wherein the gas cryogen flows through the secondary reservoir tube,
- wherein the primary reservoir and the secondary reservoir are located inside of the heat shield portion, and the primary reservoir and the secondary reservoir are thermally shielded by the heat shield portion from the external conditions, and
- wherein all outside surfaces of the secondary reservoir are spatially separated from the heat shield portion.
