It was shown that to eliminate the formation of a discharge channel in a gas at high pressure it is necessary to have prior to discharge many initiating electrons distributed over the cathode or throughout the volume of the discharge gap. For this purpose it was proposed to use a beam of fast electrons. The report presents the results of a study of discharge in nitrogen at pressures up to 16 atm.abs., initiated by a beam of electrons with an average energy of 100-350 keV. A channel-free form of discharge was obtained with voltages above 100,000 V and switching currents of some tens of kiloamps.
