Abstract

See full text

In a method and apparatus for maintaining operation of ancillary equipment associated with a superconducting magnet carrying a DC current, the DC current is directed through a DC-to-AC converter, and the magnitude of the current flowing through the superconducting magnet is ramped down at a controlled rate, thereby generating a controlled voltage across a controlled impedance, and powering the ancillary equipment by the controlled voltage and an associated current, and the ramping rate is controlled in order to maintain a required controlled voltage.
