MAGNETIC FLUX PUMP EQUIPPED WITH HIGH-TEMPERATURE SUPERCONDUCTOR AND SUPERCONDUCTING ELECTROMAGNET

摘要

PROBLEM TO BE SOLVED: To obtain a means of realizing a device by the use of high-temperature (HTC) superconducting material, wherein the device is equipped with a transformer and a magnetic pump (2) formed of a rectifying circuit equipped with a controllable switch provided on its secondary side to feed a current to the superconducting coil (11) of an electromagnet (111) for forming a magnetic field of high stability.;SOLUTION: The secondary windings (213 and 313) of a transformer (13) and switches (15, 16, 115, and 116) are formed of HTC superconducting material, and the switches are controlled for stabilization by a heating device (48), especially by a trigger pulses (D') in rectifying rhythm. The magnetic flux pump and a superconducting electromagnet to which the magnetic flux pump feeds a current are arranged in the same cryostat (100).;COPYRIGHT: (C)2002,JPO
