CALCULATING GLOW DISCHARGE PLASMA PARAMETERS IN AN ARGON ATMOSPHERE FOR THE URAGAN-2M STELLARATOR

Numerical calculations of the parameters of the glow discharge plasma were carried out on the basis of a global volume-averaged model. The calculations were carried out for argon, and iron, the main component of stainless steel, was assumed as the cathode material. The electron temperature and density, the density of sputtered iron atoms and iron ions, and the density of metastable argon atoms were calculated as a function of pressure and adsorbed power in the discharge. The results of the calculations of the electron temperature and density were compared with the results of previous experiments and are in satisfactory agreement.
