SUPERCONDUCTING MAGNET DEVICE, AND QUENCHING DETECTOR AND DETECTION METHOD OF SUPERCONDUCTING COIL

摘要

PROBLEM TO BE SOLVED: To perform quench detection more accurately than conventional methods.;SOLUTION: The superconducting magnet device 1 comprises: a superconducting coil 11; and a first voltage difference detection unit DU(1). The first voltage difference detection unit DU(1) detects the voltage difference of a voltage between a first endpoint EPA and a first division point DPA of the superconducting coil and a voltage between a second endpoint EPB and a second division point DPB of the superconducting coil. The first division point DPA is located on a coil conductor between the middle point MP and the first endpoint EPA of the superconducting coil. The second division point DPB is located on a coil conductor between the middle point MP and the second endpoint EPB of the superconducting coil, and is symmetrical to the first endpoint EPA with respect to the middle point MP.;COPYRIGHT: (C)2013,JPO&INPIT
