Abstract

The invention discloses a method for testing the multi-field coupling performance of a tritium-blocking coating based on accelerator ion irradiation and a testing device thereof. The method is to use the accelerator to generate energy-carrying ions to irradiate the tritium-resistant coating sample; the gas injection system injects the gas medium into the flange to infiltrate the tritium-resistant coating sample; the temperature control system controls the heating table to irradiate the tritium-resistant coating. The samples are thermally cycled; then processed by the computer program control system. The device includes an electrostatic tandem accelerator, a vacuum chamber, an infrared thermometer, a sample stage, a gas injection system, a temperature control system, a computer program control system and various signal transmission lines; it realizes the multi-field coupling performance test of the anti-tritium coating. The test method and test device of the present invention can realize the multi-field coupling performance test of ion irradiation, thermal cycle and gas permeation on the fusion reactor tritium-resistant coating sample; thus more reliable and accurate evaluation of the tritium-resistant coating in service under actual working conditions Performance, with research and practical application value.

Description

technical field [0001] The invention belongs to the field of research and application of fusion reactor materials, and in particular relates to a multi-field coupling performance test method and a test device for a fusion reactor tritium-blocking coating based on accelerator ion irradiation. Background technique [0002] Anti-tritium penetration and tritium safety protection are important technologies to be solved urgently in the design of fusion reactor tritium breeding cladding. In order to effectively solve the problems caused by tritium penetration, it is necessary to coat the surface of the tritium circuit structural material with a tritium-resistant coating. Compared with the tritium circuit system outside the reactor such as tritium separation and purification, the tritium-resistant coating in the cladding of the fusion reactor is close to the plasma region, and the working conditions are the most complicated and harsh. Serving in working conditions, it is very prone ...
