A superconducting magnet assembly comprises a superconducting magnet which, under working conditions, generates a magnetic field in a working volume. The superconducting magnet is connected in parallel with a series combination of a superconducting fault current limiter and a resistor, and with a DC power source. Under working conditions, the magnet can be energized by the power source to generate a desired magnetic field in the working volume.

Apparatus for quench protection and stabilizing decay in a quasi-persistent superconducting magnet

An electromagnet comprising a plurality of coils of superconductive material, monolithically embedded in an embedding material, which is solid at the temperature of operation of the superconductive electromagnet, and a method for producing an electromagnet comprising a plurality of coils of superconductive material, comprising the steps of winding coils of superconductive material, retaining the coils at predetermined relative positions, and monolithically embedding the plurality of superconducting coils in an embedding material, which is solid at the temperature of operation of the superconductive electromagnet.

Electromagnet

A resin-impregnated superconducting magnet coil comprising a number of turns of superconducting wire () embedded within a resin () having an outer filler layer () composed of the resin, filled with filler material (). The coil further comprises a cooling layer () interposed between the superconducting wire () and the filler layer ().
