Abstract
A portable magnet power supply for a superconducting magnet includes apparatus for the storage of energy released from a superconducting magnet, the apparatus having an electrical run-down load for connection across the electrical terminals of a superconducting magnet; and a heat storage material in thermal contact with the run-down load; and a method for use thereof.
Claims10
A portable magnet power supply for a superconducting magnet comprising apparatus for the storage of energy released from a superconducting magnet, said apparatus comprising:
- an electrical run-down load for connection across the electrical terminals of the superconducting magnet to receive energy released from the superconducting magnet in a ramping down of the superconducting magnet in a ramping down time span;
- a heat storage material in thermal contact with the run-down load, said heat storage material having a heat storage capacity that stores substantially all of said energy in said ramping down time span;
- and
- a housing in which said run-down load and said heat storage material are contained, said housing being configured to be manually portable and said run-down load and said heat storage material having a size and weight configured for manual transport of said run-down load and said heat storage material in said housing.
A method for removing energy from a superconducting magnet using a portable magnet power supply, comprising:
- manually bringing a non-stationary, portable magnet power supply to a site of a superconducting magnet, said portable power supply having a housing containing a run-down load and heat storage material;
- connecting said run-down load of the portable magnet power supply across electrical terminals of the superconducting magnet;
- in a ramping down of said superconducting magnet opening a superconducting switch to divert current flowing in the superconducting magnet through the run-down load, said current having an energy associated therewith and said ramping down procedure taking place in a ramping down time span;
- storing substantially all heat generated by the run-down load in response to the current flowing through it during said ramping down time span in the heat storage material of the portable power supply;
- and
- allowing the heat storage material to cool after current has ceased to flow through the run-down load.
