10. Review of quench detection methods in superconducting magnets (20'+5')

Felix Rodriguez Mateos (CERN)

11/09/2015, 09:00

This talk gives a summary of quench detection methods used so far in superconducting magnets, both in already operating facilities and in experimental test stations. An special emphasis will be given to quench detection issues in large scale, superconducting magnet machines like LHC and the future ITER. Results from experiments specifically designed for studies and from operational experience...

11. A New Detection Method of Normal Transition in HTS Coils by using Poynting's Vector Method (20'+5')

12. Optical fibers for quench detection (20'+5')

Justin Schwartz (NC State University)

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...
