SENSOR FOR DETECTING A QUENCH IN A SUPERCONDUCTOR USING AN OPTICAL COUPLING |
摘要 |
55,095 A quench detector for a superconducting coil is provided which utilizes an optical coupling and a rotary encoder. The presence of a resistive voltage in the superconducting coil created by a quench will cause a rotatable readout coil to move. Movement of the readout coil will be detected by light passing through or reflected by an optical encoder, which will interrupt or transmit light passing from one or more light sources towards one or more light sensors. Preferred embodiments utilize optic fibers for the light sources and sensors, which are unaffected by the high magnetic fields or hostile environment of the superconductor coil.
