Abstract

The algorithm and calculation results of gas flow in hollow cathode in vacuum chamber under gas discharge ignition are represented. The preliminary estimations show breakdown and ensuring ignition of smoldering discharge to be occurred, when the gas flow streaming from cathode reaches the anode with forming the area of the raised pressure. Under this the conditions corresponding to the minimum Pashen´s curve for given breakdown voltage are realized in anode-cathode gap. Comparison of calculated gas flow and experimental sightings of gas discharge show the prevalent role of gas dynamics to form the conditions of discharge ignition following maintenance.
