Abstract

Multipoint temperature measurement of the superconducting wire was demonstrated to detect quench behavior utilizing a multiplexed fiber Bragg gratings sensor. The sensor was directly attached on the wire to measure actual wire temperature during the quenching. Quench propagation was successfully detected by measuring delay time of temperature increase on each grating.
