A method of kinetic description of the near-wall plasma and non-local effects

As is known, ion kinetics play an essential part in the formation of a near-wall plasma layer. The scatter processes with ions involved (ionization, recombination, charge exchange, etc.) influence both the value of the near-wall potential jump (and, accordingly, the value of the electric field on the surface) and the unipolar arc formation. The applicability of the Bohm criterion which is widely used in many works, also depends on the processes of ion scattering. In this paper a new method of the ion kinetics in a magnetic field is proposed which can been applied to the problems mentioned above.
