A 19T REBCO insert coil for the 33T cryogen-free superconducting magnet (33T-CSM) is operated in approximately 15 K due to its AC losses duaring ramping. For this reason, it is important to fully understand the critical current characteristics of the REBCO tape used in the low-temperature, high-magnetic-field region. In this report, we present the low-temperature, high-magnetic-field characteristics of the REBCO tape (Fujikura FESC-SCH04(40)) for the 19T-REBCO insert coil.
