Improved method of specifying the source of heat in the simulation of flows in the cathode operating conditions on the nodes using the approximation of the field strength along the length to calculate the intensity of volumetric heat source of the problem and the original domain of validity using the R-functions. In the modeling of a segmented cathode node is shown that the operating modes mechanism of penetration of reactive gases in the cathode region is significantly different from the cold blowing. In the working-purpose flow of shielding gas should be given to the complex. On the example of a model problem shows that the effective protection of the thermionic hollow cathode operating conditions possible for pa-hunok increase of inert shielding gas to 4.67 times. The necessity of revision of existing models to account for the dependence of the emission characteristics of temperature and gas composition. The problems of integration of the physical processes at the plasma - solid. A numerical model for calculating the parameters of free-fall of yuschego in an argon plasma arc light emission properties of c of the cathode material and the deviations from LTE in the near-electrode zones.
