Formation of Electron Beam and Volume Discharge in Air under Atmospheric Pressure.

摘要

The conditions to form electron beams in air, nitrogen, and in the mixture CO2 - N2 - He under atmospheric pressure have been examined experimentally. At nanosecond pulses applied to the diode, e-beam was obtained in air with amplitude of 70 Angstrom. Electron beam appears at voltage pulse leading edge having duration at FWHM not higher than 0,4 ns. After beam current ends, the discharge is usually continued in quasi-stationary mode being of a volume character.
