摘要： PURPOSE:To accomplish a permanent current switch at high speed and with low heat emission, suppress heat intrusion of refrigerant He and evaporation associate therewith, and control the operation time easily with the peak value of the input power. CONSTITUTION:A thermal type permanent current switch 3 is composed of a superconductive wire 3a and a heater wire 3b. When the current in the superconductive wire 3a is to be shut off, first a large power is applied to the heater wire 3b to quickly transfer a superconductive coil 1 from the superconductive state into normal conductive state, and then the power to the heater wire 3b is reduced so as to apply the min. power for keeping the normal conductive state.

摘要： PURPOSE:To provide a gas cooling type current lead, to be used for a superconducting coil, having the low heat load in cooling system by suppressing the Joule heat generated by the application of a DC current and the heat intruding into the low temperature side from the normal temperature side, and also decreasing the consumption of a liquid refrigerant (liquid helium). CONSTITUTION:An outer cylinder 9 and an inner cylinder 11, which form a refrigerant gas flow passage, are arranged between a low temperature side terminal 6 and a normal temperature side terminal 7 as the gas cooling type current lead 5 of a superconducting coil which supplies a current from the AC power source on the normal temperature side for the superconducting coil which is forcibly cooled to a cryogenic temperature by dipping into the liquid refrigerant in a cooling vessel. A lead wire 8, which links between terminals, having a number of strands in a bundle, is dispersively arranged on the outer circumferential surface of the inner cylinder. The low temperature side terminal 6 is formed into a cylindrical body, a slit 6a is formed on its circumferential surface, the concentration of current due to the skin effect of an alternating current, and the intrusion of heat from the normal temperature side where the current lead is used as a heat transfer path, and the eddy current loss caused by alternating magnetic flux can be suppressed low, the heat load of the cooling system is decreased, and the amount of consumption of a refrigerant can be economized.
