Abstract

This paper describes a superconducting power supply (flux pump) of the transformer rectifier type in which the rectification is produced by thermal switching. The supply is intended for use with a superconducting magnet. At an operating current of 1000A the pump can charge a magnet at about 20 W with an efficiency greater than 93%. In separate battery tests the pump has developed 38 W at a current of 1500A. Design of an improved 1500A, 500 W supply is in hand.
