Temperature uniformity characterization in heat treatment of the Nb<sub>3</sub>Sn coils for nuclear fusion
Abstract Burning plasma Experimental Superconducting Tokamak (BEST) is a full superconducting coil tokamak. The heat treatment of the Nb 3 Sn coils of the BEST is carried out by using an atmosphere-protected heat treatment furnace. The temperature uniformity throughout the coil becomes a crucial problem due to the large size of the cross-section of the coil. In this study, the temperature uniformity characterization experiment of the Nb 3 Sn coils was carried out to simulate the actual coil heat treatment condition. The test results show that the temperature gradient of the cross-section of the coil is within 3°C, which provides data for further optimization of heat treatment of the coils of BEST.
