The results and analysis of experiments are presented, the purpose of which is to study the mechanism of ignition of a high-voltage arc discharge in a vacuum gap. The results indicate that the development of an arc discharge under the presented conditions is occurs mainly due to the ionization of the residual gas by a flow of overheated electrons with an energy of ~ 100-500 eV from an auxiliary spark discharge. Keywords: vacuum arc, spark discharge, plasma, magnetic field. DOI: 10.61011/TPL.2023.09.56707.19637
