Plasma facing experimental part with reference corner structure

Abstract

The invention discloses a plasma facing experimental part with a reference corner structure. The plasma facing experimental part comprises an experimental part and a reference corner arranged at one end of the experimental part, wherein the reference corner is an attenuation structure reserved on the experimental part in the event of processing the experimental part; one surface of the reference corner is used as the original surface; one surface of the experimental part is used as an experimental surface; and a mark for experiments is arranged on the original surface. According to the invention, corrosion, deposition, impurity migration and retention of materials are represented by cutting off the reference corner, taking related data of the surface, the side surface and the body of plasma as original data, and referring and comparing the original data with the data of the experimental part subjected to a plasma irradiation experiment before carrying out the plasma irradiation experiment. The plasma facing experimental part has the advantages of being simple and easy for design, convenient for processing and better in comparison and can be applied to testing of a plasma facing material in a nuclear fusion experimental device and an interaction experiment between the plasma and a wall material.

Description

technical field [0001] The invention relates to a nuclear fusion experimental device, in particular to a plasma-facing experimental component with a reference angle structure. Background technique [0002] Materials are one of the key issues on the road to realizing fusion to the ultimate practical use. In the fusion device, the PFM directly faces the plasma and interacts with the plasma, which is prone to various PWI modification changes, which affects the service life of the PFM, and the escaping impurities may also endanger the stability of the plasma and the stability of the fusion device. Safe to run. The PWI problem is also considered to be one of the most critical issues in the construction of the International Thermonuclear Experimental Reactor (ITER) project. Its mechanism of action includes sputtering, injection, melting, evaporation, adsorption / desorption, Diffusion / capture, aggregation and foaming, hydrogen precipitation at grain boundaries, neutron irr...
