Limiter for test platform for interaction of fusion reactor plasma and material

Abstract

The invention discloses a limiter for a test platform for interaction of fusion reactor plasma and a material, the limiter comprises a vacuum chamber, a plurality of mounting rails are arranged radially on the inner wall of the vacuum chamber, and a panel is further arranged inside the vacuum chamber. The panel is a circular double-layer structure, a cooling pipe is arranged inside the panel, a flange is fixed in the middle portion of the panel, a circular hole is formed in the center of the panel, and the diameter of the circular hole is 5 to 100 mm. The left ends of the plurality of mountingrails are fixedly connected to the panel. The self-cooling performance is added in the limiter, that is, cooling water is introduced in a cooling pipe arranged inside the limiter to reduce the temperature of a joint portion of the limiter, a part of a divergent ion source can be filtered to allow the divergent ion source to more concentratedly to pass through a small hole in the middle of the limiter, and can be adjusted by replacing the limiter flange, and the limiter has the advantages such as adjustable distance from the plasma source, flexible operation, simple and reliable structure.

Description

technical field [0001] The invention relates to the technical field of application of fusion reactor plasma and material interaction testing devices, in particular to a limiter for a fusion reactor plasma and material interaction testing platform. Background technique [0002] The working mechanism of the fusion reactor plasma-material interaction test platform is: after the cascade arc plasma source is powered on, the plasma beam is released. Under the action of the magnetic field of the superconducting magnet, the plasma moves along a straight line and hits the preset position that is the target. plate material to analyze possible changes in the material. [0003] Due to the uncertainty of the running direction of part of the plasma in the magnetic field, the plasma density at the edge of the plasma beam decreases, so that when it hits the target plate, the plasma density at the edge of the plasma beam cannot meet the requirements, that is, the plasma density at the edge o...

Problems solved by technology

[0003] Due to the uncertainty of the running direction of part of the plasma in the magnetic field, the plasma density at the edge of the plasma beam decreases, so that when it hits the target plate, the plasma density at the edge of the plasma beam cannot meet the requirements, that is, the plasma density at the edge of the plasma beam cannot meet the requirements. The average heat load to the target plate does not meet the predetermined requirements
