Conditions near the boundary between plasma and wall: kinetics of ions and electric potential distribution

The paper suggests an exacting theory of phenomena near the plasma interface with solid surface. General expression for ion distribution function by rates in near-the wall plasma which is true at arbitrary frequency of scattering and takes account of possible strong distortions of function of ion distribution near the wall is determined with regard for recharging and ionization (recombination) processes. Asymptotic dependences of plasma parameters - electrical potential, density of ions, etc. - at a distance from the wall - are determined on the basis of space dependence of ion density obtained from function of ion distribution and in the assumption about Boltzmann character of electron distribution. 10 refs., 4 figs
