Description

technical field [0001] The invention belongs to the technical field of thermonuclear fusion reactors, and in particular relates to a thermonuclear fusion reactor superconducting coil thermal shielding part and a preparation method thereof. Background technique [0002] ITER is currently the largest superconducting tokamak device in the world. In the ITER facility, the magnetic confinement of the plasma is achieved by means of different superconducting coils. The fusion reactor magnet system includes 18 correction coils. These superconducting coils must be kept below extremely low temperatures to maintain superconductivity and maintain the stable operation of the ITER device. However, each poloidal field coil box in contact with the correction field coil generates about 16.596kW of heat under the magnetic field, in order to ensure the normal operation of the correction field superconducting magnet during the operation of the fusion reactor. The thermal shielding part connec...
