The studies of exposing of targets by hot-electron plasma exhaust from the multi-mirror trap GOL-3 are carried out. In experiment conditions the energy density affected the target placed in facility chamber can be varied within 1– 30 MJ/m2 per shot. In the paper the results of Raman and SEM studies of surface modification of carbon materials with different ordering range of sp2 fraction (finegrained graphite and glassy carbon) exposed by hot hydrogen plasma with energy density up to 8 MJ/m2 are presented. It is shown that on the depth up to ~80 nm due to this exposing there are obtained two effects – micro structural destruction of the surface and extension of crystallite size of sp2 phase, i.e., ordering of nanostructure.
