ABSTRACT
The surface ionization of plasma particles is known to affect to a considerable extent characteristics of the near-anode region of discharge. It may be of importance for understanding near-electrode processes and the phenomenon of the electrical break-down between plasma and solid surface. Rough calculations of the surface photoionization coefficient have been performed omitting adsorption kinetics. Thus, the investigation performed on the model presented demonstrates that the kinetic approach permits describing the regularities of laser-assisted surface ionization and determinating the bond energy, ionization and recombination probabilities which are of necessity for the calculations on the basis of comparing the experimental and theoretical values. Since the surface ionization strongly affects the distribution of ion density throughout the near-electrode area laser-assisted surface ionization may be as a highly important factor that controls its characteristics.
