Optimization of the electron beam parameters and choice of the foil in electron-beam-controlled lasers

The passage of relativistic electrons through the foil-gas-anode system in an electron-beam-controlled laser was analyzed by the Monte Carlo method. A study was made of the influence of the beam parameters, composition of the active medium, electric field in the nonself-sustained discharge, and also laser design features on the ionization homogeneity in the discharge gap and the uniformity of the electric field in it. A discussion is given of the choice of the beam energy and of the construction elements of a laser using light foils.
