Description
Due to the combined superior electrical and mechanical performance, ReBCO tapes are considered as a candidate material for application of high current carrying magnets operation under high magnetic field. However, the high aspect ratio and multilayer structure of the tape complicate its cable and CICC conductor design and manufacturing. It is therefore important to carry out activities to investigate its high field application performance. Thus, ReBCO insert solenoids are taken as prototypes and have been developed in ASIPP, which were wound from ReBCO cables. Afterwards, the critical current of the manufactured solenoids were measured at 77 K, self-field and 4.2 K, a background field of 10 T and 19 T. Effects from the developed manufacturing technologies, electromagnetic and thermal loads during operation on the current carrying stability were assessed and summarized here. The results show that the manufactured solenoids critical currents are stable over dozens of electromagnetic and thermal cycles, which represent a key milestone in next step HTS magnet technology development for high field application.
