Plasma from Electron Beam Evaporation of a Metal Target

Abstract:

Transport variables in plasma column are analytically investigated in this paper. Low-energy electrons and ions are produced from electron beam evaporation of a metal target in the technological vacuum chamber of an electron beam welding machine. Assuming collisionless plasma motion in the radial direction, the electrostatic potential is obtained from model of plasma expansion. Transport variables such as ion density, electron density, conduction heat of the ions and electrons are calculated using the electrostatic potential and are compared with the available experimental data.
