Poster

This work analyzed current sharing and quench evolution in REBCO based superconducting cables intended for use in the High Energy Physics (HEP) accelerator dipole magnets. Current sharing was explored for simple tape stack cables using FEM modelling. Summaries are given for finite element work performed on various number of stacked tape cables, in 3D configurations while varying interstrand...

Poster

Detecting quenches in superconducting (SC) magnets during training is a challenging process that involves capturing physical events that occur at different frequencies and appear as various signal features. These events may be correlated across instrumentation type, thermal cycle, and ramp. These events together build a more complete picture of continuous processes occurring in the magnet,...

Invited Poster

High-temperature superconducting (HTS) magnets are designated for use as Central Solenoid (CS) magnets in China’s next-generation fusion device. However, their temperature rises rapidly when quenching happens, which may lead to performance degradation. So the voltage detection threshold of HTS is much lower than LTS magnets. The currently employed Co-wound Wire (CWW) + Inductive Noise Realtime...
