Abstract: Superconducting conductor experimental testbed (Super-X) is an important part of the comprehensive research facility for fusion engineering (CRAFT), and is used to evaluate the performance of future superconducting conductors. The superconducting magnet of the Super-X test facility consists of Nb₃Sn coils, which are fabricated by“winding & heat treatment”. An argon protective atmosphere heat treatment system for Nb₃Sn coil heat treatment was designed and built, and successfully completed the heat treatment of low field coil. The uniformity of heat treatment temperature meets the requirement of ±5 ℃, the impurity gas content of coil is less than 10 mg/L, and the impurity gas content of furnace is less than 30 mg/L. The properties of the furnace specimens after heat treatment all meet the expected goals, and the distortion of the coil before and after heat treatment is less than 2 mm.

Key words: Nb₃Sn, superconducting coil, heat treatment, Super-X
