Abstract
Using superconducting magnetic flux pump, thick power leads for a superconducting magnet could be replaced with thin string leads for the excitation magnet to the superconducting flux pump. We have developed a new type flux pump with high voltage output to shorten the charge and discharge time of the load magnet. The test of four stacked disks as the excither for the load magnet has been carried out. This disk type flux pump yielded 70 mV of voltage across its terminal and 10 A of current through 85 mH load magnet which was the field winding of 20 kVA class fully superconducting generator within 12 seconds. This output voltage of the new superconducting flux pump is about 10 times larger than that of the previous work Moreover since it is easy to stack the disks for the superconduction flux pump, the high voltage exciter for the 1H class superconducting magnet would be expected to be made easily.
