Description

Due to slow quench propagation, early quench detection remains an unresolved challenge for HTS magnets. An emerging new approach, co-wound optical fibers interrogated via Rayleigh scattering, offer very high spatial and temporal resolution and the ability to detect a disturbance before the hot-spot temperature exceeds the current-sharing temperature. This talk will review recent progress on this technique, discuss the remaining challenges and possible solutions.
