A plasma-beam discharge during electron beam injection in a rarefied gas
Abstract
Electron beam transport in a rarefied gas was studied experimentally for beams with currents up to 0.8 A and energies of 10 keV at pressures of 0.00001-0.001 torr. The parameters of the beam-plasma discharge and the spectrum of waves excited by the beam-plasma interaction in the range up to 10 MHz are determined. Attention is also given to the stimulated beam-plasma discharge generated in a system with electrostatic plugs, which is characterized by a substantial reduction of the beam current threshold.
