The common wall materials at present are stainless steel, high-melting point metals and alloys thereof, and the materials with medium and high atomic numbers are sputtered under the action of plasma and neutral particles, and generated heavy impurities are gathered in a plasma core, so that energy loss can be caused, and unstable and even cracking of the plasma can be caused. The carbon-based material with low atomic number has the advantages of high heat conductivity, high thermal shock resistance, certain strength at high temperature, good compatibility with plasma, high bearing capacity for plasma cracking and edge area die, and the like. By using a carbon-based material as a wall covering material or restrictor, the vacuum chamber wall can be effectively protected.
In view of the good performance of carbon-based materials, a certain effect is achieved by covering the inner wall of a vacuum chamber with high-purity graphite tiles on some large-scale devices, but the carbon-based materials have higher porosity and higher adsorptivity to deuterium and tritium, and seriously influence the combustion of deuterium and tritium to-be-produced ionic bodies.

In view of this, the present application is specifically proposed.
