en.Wedoany.com Reported - The on-site acceptance test for the MCTB cold magnet test power supply system of the ITER project was successfully completed. This project was jointly delivered by three contractors: Rongxin Huike Electric Co., Ltd. (RXHK) from China, the Institute of Plasma Physics of the Chinese Academy of Sciences (ASIPP), and Hefei Rongke Hengyang Power Supply Technology Co., Ltd. (RHR).

Within the ITER magnet cryogenic test facility, superconducting magnets need to be cooled to the extreme low temperature of 4 K (-269 °C). Simultaneously, an electrical system with high-power output and precise control capabilities is required to deliver currents as high as 68 kA. This is used to simulate the electromagnetic stress and thermal load conditions that the superconducting magnets must withstand during tokamak operation. This capability is a prerequisite for conducting magnet performance tests and is directly related to the safety and stability of the Toroidal Field (TF) coils in the extreme cryogenic environment.

The commissioning of this power supply system has laid the technical foundation for the subsequent cooling and testing of TF Coil #7, effectively reducing the engineering risks associated with energizing the superconducting magnets within the device. According to the plan, the cooling work for TF Coil #7 is scheduled to commence in late April, with magnet testing expected to officially begin in May.
