“…The theoretical calculation used to interpret the results of the present experiment was based on methods introduced in Dnestrovskii et al (1972), Hackmann et al (1978a and Rehker & Wobig (1973) for tokamak plasmas and is also applicable to the present experimental conditions. The neutral velocity distribution was obtained from the numerical integration of the corresponding onedimensional Boltzmann equation with presumably known background parameters n e>i (x), T ei (x) of charged particles taking into account charge transfer and ionization.…”

The influence of a metallic wall on the velocity distribution of the neutral particles in a plasma has been experimentally determined by spectroscopic measurements of a Doppler broadened line. Typical characteristic facts of the plasma –wall interaction can be explained quantitatively by means of a one-dimensional kinetic equation, which is solved in the plasma –wall interaction region, assuming reasonable boundary conditions on the wall surface.
