According to the test results, the CICC conductor sample exhibited a stable performance regarding the current sharing temperature. Under the typical operational conditions of a current of 45 kA, a magnetic field of 4 T and a temperature of 5 K for PF2, the test result for the conductor current sharing temperature is 6.71 K, with a temperature margin of 1.71 K. For a comparison thermal-hydraulic analysis of the PF2 conductor was carried out using GANDALF code in a 1-D model, and the result is consistent with the test one.展开更多

The sample was made of two TF conductor sections manufactured from identical internal stannum strands provided by the Oxford ~upercon- cluctlng technology company （OST）. In order to evaluate the conductor performance, the current sharing temperature （Tcs） was measured at specified electromagnetic load cycling steps. Both conductor sections of the CNTF1 sample showed identical performance. Tcs was 7.2 K before cycling loading, and 6.9 K even after 950 cycles, without significant degradation, which substan- tially exceeds the ITER requirement of 5.7 K. The tests of the CNTF1 conductor sample showed that the electromagnetic cyclic load exhibited a negligible effect on the conductor performance. The coupling time constant 0 for AC loss was 214 ms and 71.52 nrs before and after the cycling load. respectively. The test results of the sample are compared with the strand performance and parameter model analysis.展开更多
