THE LINEAR ACCELERATORS REVIEW

The stationary linear plasma simulators was reviewed, which are used to study the interaction between plasma and surface with regard to fusion facilities and modeling of their edge plasma. The interaction between plasma and surface is an important issue in creation of protective materials for the International Thermonuclear Experimental Reactor (ITER). The first wall and divertor are the key plasma faced components. The basic functions of the divertor are a heat flux absorption released from the edge plasma and helium removal, which is a combustion product in the thermonuclear synthesis reaction. Relatively small facilities with limited capacities as well as large linear simulators with a capacity of several dozen of kW and various diagnostic tools have been considered separately. Since the modern linear installations have a temperature and density of the generated plasma close to SOL plasma (scrap-off layer), it is possible to research the processes which directly affect materials of the components. This is a modification of surface during plasma irradiation or with charged particle beams. This includes atomization of a surface and studying of erosion, penetration of foreign particles into the surface or coating, surface relief modification, blister generation.
