Longitudinal electron energy distribution

An electron lattice energy analyzer is designed and assembled for the PR-۲ linear plasma device. The analyzer is used to measure the electron longitudinal energy distribution function (EEDF) of beam-plasma discharges and can detect energies up to ۱۰ kV. The EEDF was obtained for different electron gun accelerator voltages of ۶۰۰-۱۵۰۰, while the electron gun emission pressure and current were fixed during the experiments. Two modes of plasma beam discharge were observed depending on the accelerating voltage of the electron beam gun. A significant part of the electrons have more energy than the beam energy due to the beam-plasma interaction.
