Abstract

During a field ramp of a ReBCO magnet, the heat dissipated by conductor AC losses may affect the magnet operation temperature, and significantly increase the liquid helium consumption. Therefore, the calculation and measurement of AC losses of ReBCO coils are very important. Understanding the AC losses behavior of ReBCO coils will allow prediction of AC losses for future ReBCO magnets.
