APPARATUS FOR QUENCH PROTECTION AND STABILISING DECAY IN A QUASI-PERSISTENT SUPERCONDUCTING MAGNET

摘要

A superconducting magnet assembly comprising a superconducting magnet (1) which, under working conditions, generates a magnetic field in a working volume, the superconducting magnet being connectedin parallel with a series combination of a superconducting fault current limiter (7) and a resistor (5). The magnet is further connected in parallel to a DC power source (4) whereby under working conditions, the magnet can be energised by the power source to generate a desired magnetic field in the working volume.
