摘要：

When a quench occurs in a superconducting magnet, excessive joule heating may damage the magnet. The authors have presented a quench detection/protection system based on an active power method, which can detect the quench quickly and precisely by measuring an active power dissipated within the magnet after the quench. in this paper, the authors show usefulness of a software quench detection/protection system for a cryocooled NbTi superconducting magnet which is a commercial size magnet made by Tamakawa Co., Ltd.. Experimental results show that the proposed system is useful for the practical used superconducting magnet. (C) 2012 Published by Elsevier B.V.
