A physical model of cathode arc initiation by a discharge over the dielectric surface with allowance for the presence of residual gas molecules in the discharge gap is presented. This made it possible to determine the degree of residual gas influence on the initiation processes and to calculate the dependence of the auxiliary discharge ignition voltage on pressure. A comparison of the results of modeling with experimental data is given.
