To the Optimization of Quench Performance for a Large REBCO Cable-in-Conduit Conductor

Abstract

REBCO conductors at the level of tens kiloamperes are being developed for their application in fusion magnets. One important aspect to study is their performance in the case of a quench event happens. A conductor should survive from such an event without over design; therefore, they should be properly optimized. Using a simulation model developed based on THEA code, we studied the parameters of a REBCO conductor in a fusion magnet for their influence on the quench performance, evaluated by hot spot temperature and quench detection. According to these results, the principles to the optimization of quench performance of a REBCO conductor are discussed.
