Abstract
Pulse charge tests of an ITER Central Solenoid (CS) Model Coil and a CS Insert Coil, hereafter referred to as CSIC, have been carried out in the CS Model Coil experiment, which was conducted by Japan Atomic Energy Research Institute in 2000. Both coils were successfully operated up to 13T with the designed ramp rate of 0.4T/s. Also, ramp rate limitation (RRL) tests were performed for both coils. The RRL test results of CSIC are reported in this paper since the AC loss and critical current evaluation of this coil has been almost completed. The results indicate that CSIC quenches at lower currents than those that were expected to be the critical current, taking into account the temperature rise by the AC losses in the much faster pulse operation than the designed. Moreover, the ratio between the quench and critical currents decreases with increasing ramp rate.
