Abstract
A cooling system and a superconducting magnet apparatus employing the same. The cooling system includes: a thermal shield unit for thermally shielding a superconducting coil; a recondensing unit for recondensing an extremely low temperature refrigerant that cools down the superconducting coil. A cryocooler includes a body and an end portion extending from the body and inserted into the recondensing unit in order to directly contact the extremely low temperature refrigerant. A refrigerator chamber penetrates through the thermal shield unit and to which the cryocooler is attachably and detachably provided. A sealing member is disposed between the cryocooler and the refrigerator chamber to seal the recondensing unit.
