The influence of the nitrogen pressure on the breakdown voltage in a nonuniform electric field is studied. Voltage pulses with nanosecond and subnanosecond rise times are applied to the gas gap. Simultaneously with the application of voltage pulses, supershort avalanche electron beam are observed behind a foil anode. It is found that, when a runaway electron beam is generated and voltage pulses have a subnanosecond rise time, the breakdown voltage rises as the nitrogen pressure decreases from 677 to 1 Torr. Experimental data are in good agreement with pulsed breakdown analytical curves.
