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.

Example Embodiment

[0017] Such as figure 1 As shown, the present invention includes an experimental component 1 and a reference angle 2 set at one end of the experimental component 1. The reference angle 2 is a subtractive structure reserved on the experimental component 1 when the experimental component 1 is processed.
[0018] The material of the experimental component 1 is a plasma-facing material, preferably graphite, or molybdenum, or tungsten. During the experiment, the reference angle 2 is eliminated and mounted on the first wall of the tokamak device, and the surface is flush with the first wall.
[0019] The side of the reference angle 2 is used as the original surface 4, and the side of the experimental part 1 is used as the experimental surface 3. The original surface 4 and the experimental surface 3 are provided with the same experimental marks, and the surface part outside the experimental marks is the same as the experimental field Other common surfaces with the same surface of the first wall or divertor; the experimental marks on the original surface 4 and the experimental surface 3 can be common marks, and the experimental marks are preferably coatings, grooves, and counterbores.
[0020] Reference angle 2 is reserved during the processing of experimental parts and the preparation of experimental marks, so the material is the same as that of the adjacent experimental parts, and the surface preparation conditions of the adjacent experimental part 1 are the same, with the same matrix, surface structure and morphology, and experimental use mark. The reference angle 2 protrudes from the side of the experimental part 1 and is connected to the experimental part 1. It is cut after the preparation of the experimental part 1. The surface and side data can be used as the surface and side data of the experimental part after the plasma irradiation experiment. Comparative reference.
[0021] The experimental surface 3 can be on the front side facing the plasma or on the side.
[0022] In the present invention, the structure of the experimental part 1 and the reference angle 2 are prepared as a whole during the preparation process, and according to the needs of the experiment, through different experimental methods such as notching, drilling, coating, pre-corrosion, etc., adding the same structure and properties Marks for experiment, the position and size of the marks for experiment can be adjusted according to the needs of the experiment. The size of the reference angle 2 meets the requirements of post-analysis. According to the needs of the experiment, the shape, size and quantity of the reference angle 2 and the position of the side of the experimental component 1 can be adjusted.
[0023] A counterbore can be machined on the back of the experimental part 1 for inserting a temperature measuring thermocouple; a bolt hole can be machined in the experimental part 1 to realize the connection between the experimental part 1 and the back heat sink.
[0024] In the specific experiment, the reference angle 2 is cut off before the experimental component 1 is installed, and the remaining components are installed in the nuclear fusion experimental device for plasma irradiation experiments, where the nearest reference angle 2 is the experimental point.
