To evaluate the MQE, a series of conductor heating tests has been performed during the TF Insert (TFI) test campaign. TFI is a single layer about 9-turn solenoid wound from ITER TF conductor. The coil diameter is 1.44 m and the conductor length is around 40 m. TFI is force-cooled by supercritical helium inside the TF conductor. For the TFI, 68 kA current had been applied under 10.8 T background field as rated operation condition. During its operation, the conductor was inductively heated by an inductive heating coil. Through the test, MQE of the TFI has been obtained.}, title = {Minimum Quench Energy Evaluation of ITER Toroidal Field Conductor Using an Inductive}, volume = {29}, year = {2019} }
