SUPERCONDUCTING MAGNET, SUPERCONDUCTING MAGNET COIL EXCITATION METHOD AND REFRIGERANT FLOW RATE CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain a highly compact superconducting magnet, where a special power source is made unnecessary and power generation is performed by using a cooling device which is essential for setting a superconducting magnet in superconducting state.;SOLUTION: A superconducting magnet consists of a superconducting coil 3, which is cooled at a temperature equal to or lower than the superconducting transition temperature using the cooling device, and a jointing part 4 electrically connecting both terminals of the superconducting coil 3. At least a pair of a first thermoelectric element (thermoelectric power member) 1 and a second thermoelectric element (thermoelectric power member) 2 which are different in thermoelectric power are connected in series with the jointing part 4.;COPYRIGHT: (C)2001,JPO
