520 _ _ |a The hydrocarbon fluxes released from a hydrogenated graphite surface due to thermal erosion and chemical sputtering become subject to a number of particle-surface interaction (PSI) processes in the near-surface region. These processes involve an electron transfer between the released particle and the surface and, thus, affect the charge state distribution of released hydrocarbons. The electron capture from the surface by a hydrocarbon ion to an excited dissociative state can lead to prompt dissociation of the formed molecule, producing two (or more) lighter fragments. These PSI processes (of resonant and Auger type) have so far not been included in the plasma-wall interaction studies. It is, however, obvious that they play a decisive role in determination of chemical composition and charge state distribution of hydrocarbon fluxes released from the surface and entering the edge/divertor plasma region. It is equally obvious that the same processes also take place when the hydrocarbon species approach the graphite surface from the interior of the edge/divertor plasma region, thus affecting their sticking to the surface.
