In 2023, all the coil Power Supply (PS) components of JT-60SA were tested with the corresponding superconducting coils in the integrated commissioning. Initially, the individual coil energization test was carried out to confirm the performance of each coil PS component. Subsequently, the integrated coil energization test was performed step by step progressively increasing the number of superconductive coils in simultaneous operation. As a result, it was confirmed that, in the tested operation range of Operation-1 phase in 2023, set at the rated current of 25.7 kA for toroidal field coils and +/–5 kA for poloidal field coils considering the validated electrical insulating performance of the coils, all the PS components could be operated as expected. Following the successful completion of the integrated commissioning, the first plasma of JT-60SA was successfully achieved and then the plasma experiment phase started. In this paper, the highlighted results of coil energization tests in JT-60SA integrated commissioning and the achievements were reported. |
