Abstract:
1. A method of manufacturing a superconducting magnet assembly comprising: providing a housing configured about a first vacuum reservoir; forming a coil former; surrounding the coil former with a thermal shield; locating the thermal shield in the first vacuum reservoir; positioning a superconducting magnet about the coil former, wherein the superconducting magnet is configured about a central core to receive an object; providing a second vacuum reservoir having a cryogen reservoir therein; providing a first two-phase heat transfer device and a second two-phase heat transfer device, each comprising tubing having an evaporator region and a condenser region; thermally connecting the evaporator region of the first two-phase heat transfer device with one of the coil former and the superconducting magnet and the evaporator region of the second two-phase heat transfer device with the thermal shield; and thermally connecting a cryocooler to the cryogen reservoir and to the condensing region of the first and the second two-phase heat transfer devices.
