Method and apparatus for detecting quenching of a coil for a superconducting magnet

摘要

Quenching of a coil for a superconducting magnet is detected by placing a temperature sensor proximate the coil of the superconducting magnet and monitoring the temperature sensor for a rise in temperature of the coil of the superconducting magnet. AC and DC field variations of the coil of the superconducting magnet do not substantially adversely affect such temperature monitoring, thus facilitating reliable and accurate detection of such quenching. This accurate and reliable detection of quenching assures that the superconducting magnet can be shut down in a controlled manner, so as to prevent damage thereto when quenching occurs. The method and apparatus of the present invention finds particular use in maglev applications.
