The parameters of the plasma fluxes (energy density varied in the range (0.1-2.2 MJ/m2) were close to those expected in the divertor fluxes of the DEMO thermonuclear reactor.) It was found that near the irradiated surface transition plasma layers with a density an order of magnitude higher In such layers there is a partial dissipation of the energy of the incoming plasma.With moderate energy loads the surface reaches only about half of the energy of the plasma flow.With energy loads less than 0.2 MJ / m2 the transition layer consists only of particles contained in the plasma flow , impurities from the target material appear when the thermal load exceeds the melting threshold of the material.Further increase in the energy load in the form of a strong shielding of the surface by evaporated material.The stratification of the structure of capillary porous targets at an energy density in plasma over 1.5 MJ/m2 the results will be used to improve the design capillary porous components, as well as to improve numerical codes for predicting damage to surfaces in contact with plasma in a thermonuclear reactor Product Description popup.authors Eliseev Dmitry V AKSYNOV Nikolay M BIRKA Oleg V Volkova Yuliia Ye.
