    Abstract: A persistent current switch 100 including a vacuum chamber 102, a cooling unit 104 within the vacuum chamber 102 to circulate a coolant 107 between a first layer 112 and a second layer 114 of the cooling unit. The switch includes a superconducting winding unit 106 disposed on at least one of the first layer and the second layer of the cooling unit 104 to switch the persistent current switch from a normal state to a superconducting state when a temperature associated with the winding unit is below a threshold temperature. In addition, the persistent current switch includes a heating unit 108 thermally coupled to the winding unit and configured to raise the temperature of the winding unit above the threshold temperature to transition the persistent current switch from the superconducting state to a normal state. In one embodiment the switch is couple to a superconducting magnet. The cooling unit may be couple to a coolant reservoir which provides a coolant, such as liquid nitrogen, to cool the winding unit and to receive evaporated coolant. A filler material may be provided inside the cooling unit to stabilize the temperature of the winding unit. The transition between states can be done within a specific time period.

    Abstract: A superconducting magnet assembly 20 or a method of making a superconducting magnet comprises a coil former 30 adjacent to or enclosing at least one superconducting magnet 32, 34, a cryogen reservoir 74 and a two-phase heat transfer device 80B comprising tubing with an evaporation and condenser regions 84, 86. The evaporation region 84 of the device 80B is thermally connected with one of the coil former 30 and the superconducting magnet 32, 34. The condensing region 86 of the device 80B is thermally connected to the cryogenic reservoir 74 and a cryocooler 70. A vacuum reservoir 24 within a housing 22 may enclose a thermal shield 26 which may enclose the coil former 30 and magnets 32, 34. The thermal shield 26 may be thermally connected to a two-phase heat transfer device 80A. The cryogen reservoir 74 may be located in a vacuum reservoir which is shared with that of the magnets or separate and adjacent to that of the magnets or separate and remote to that of the magnets. A vacuum tube 220 may be used to insulate the cryogen 90, 92 in heat transfer devices 80A, 80B between vacuum reservoirs. The said heat transfer device 80A, 80B include tubes arranged in one or more open or closed systems. The heat transfer devices 80A, 80B may use a pulsating slug flow of cryogenic fluids.
