The first DC performance test and analysis of CC conductor short sample at ASIPP conductor test facility

The first DC performance experiments of ITER correction coil (CC) conductor short sample have been carried out in the conductor test facility of Institute of Plasma Physics, CAS (ASIPP) in January this year. Those experiments aim to investigate the DC performance of ITER CC conductor. The tested conductor short sample is bended as a half circle with the diameter of 270 mm to meet the background magnetic field shape. The half circle part of sample is longer than the final twist pitch. The current sharing temperature (Tcs) in the 3.86 T external magnetic field (Bex), ≤12 kA could be measured including the critical current (Ic) run. There is no obvious impact of 1000 cycles on DC performance. Those measured Tcs results are in agreement with the expected results from strand scaling.

► In this study the first DC performance experiments of ITER correction coil conductor short sample have been carried out in ASIPP test facility.
► A CC conductor short sample was fabricated and tested to confirm the capability of this test facility for qualification tests of CC conductors.
► There is no obvious impact of cycling on DC performance measurement.
► Those measured results of current sharing temperature are in agreement with the expected results from strand scaling
