| Abstract | ||
| The phenomenon of electrical gas discharge is present in many applications of plasma physics. Calculation of electrons motion tracing in gases are described. The backscattering probability of electrons to the cathode has been estimated for values of E/P0 ratio from 10 to 200 V.cm-1.torr-1 and for emission energies up to the lowest excitation potential. The primary ionization coefficients and drift velocities were evaluated for values of E/P0 ratio from 20 to 400 V.cm-1.torr-1. The equilibrium of swarm with the field was considered in detail. It is shown that for uniform fields, deviations from exponential growth of current with increasing electrode separation occur if the interelectrode voltage is not at least three times the mean energy of electrons impinging on the anode. | ||
