“…The corresponding anode fall (eφ in figure 3) was found to be approximately 4 eV. This corresponds well to the experimental value of 6 eV measured in a discharge with similar parameters [6]. In figure 3(b) the axial dependence of the electron and ion densities are represented.…”

“…The theory is based on the joint solution of the kinetic equation for the electrons, the momentum transfer equation for the ions, balance equations for the atoms in metastable and resonant states and Poisson's equation. A similar problem was recently considered in [6] within the scope of local electron kinetics.…”

A self-consistent one-dimensional model of the anode region of inert gas discharges at low pressures and currents is developed on the basis of non-local electron kinetics in spatially inhomogeneous fields. The model is based on the kinetic equation for electrons, the momentum transfer equation for ions and Poisson's equation. These equations are solved in the extended, non-uniform, quasi-neutral plasma disturbed by the anode and in the thin collisional sheath of space charge. The input parameters are the discharge current, neutral gas pressure and the radius of the tube. The axial profiles of the field, potential, radially-averaged densities of charged and excited particles, rates of excitation and ionizations and the ion current densities are obtained from the anode to the positive column. Two different cases are modelled which correspond to the self-consistent formation of either monotonous or non-monotonous electric field profiles. These cases correspond to different mechanisms of ion production in the sheath and the quasi-neutral plasma in the anode region. Particular calculations are carried out for neon discharges.

“…In the researches performed within recent decades (see, e.g., works [5][6][7]), a detailed simulation of processes in the AF region was carried out with regard for a balance between the generation and the loss of charged and neutral particles in the resonance and metastable states on the anode surface and the lateral walls of the GD tube, which confines the positive column and governs its existence.…”

The role of anode processes in the formation of self-organized glow discharge (GD) structure is analyzed in the case of spherical diode, the latter, as well as a short plane diode, being characterized by the absence of a positive column. The results of numerical calculations are compared with the experimental GD current-voltage characteristics and the electric field strength distributions measured by the probe method. It is shown that the boundary conditions at the anode should be formulated with regard for a possibility of a potential drop at the anode. In this case, the calculated diode potential decreases significantly and corresponds to experimentally observed results. K e y w o r d s: glow discharge, spherical diode, short diode, electric field, anode processes, fluid model, current-voltage characteristics.

Radiative efficiency of resonance line emission of a dc glow discharge plasma is derived from experimentally determined profiles of atoms in resonant states. Spatial density profiles were determined by diode laser atomic absorption spectroscopy and laser induced fluorescence. Absorption measurements were used for absolute calibration. The influence of the shape of spatial density profiles was considered. Investigations show that power dissipation by resonance radiation transport remains nearly constant for the currents investigated (i = 1 ... 20 mA). Total power loss due to resonance radiation was found to be about 25% of electrical power input.
