We have built and tested HTS common coil magnets at low field with both tapes and cable.
No significant degradation is observed at low fields, within the level of uncertainty. Early results are positive but more works need to be done.
- Build coils (~3 months) with high performance (~5x better) HTS cable which is waiting for heat treatment now at Showa
- Build coils with more turns (25) with high performance mixed strand cable we have (IGC/Showa/LBL/BNL collaboration)
- Test coils in high background field
- Build ~50 turn coils with high performance HTS cable (longer term goal). Test a set of these coils in the background field of 12 T Nb3Sn “React & Wind” common coil magnet
