Two-dimensional model of the propagation of a high-current electron beam and the acceleration of ions from a gas
Abstract
The paper presents a digital simulation of the injection of high-current electron beams into a vacuum-drift chamber and into a gas-filled chamber. The problem considered is a two-dimensional one with cylindrical symmetry for a magnetized relativistic beam in the longitudinal direction. It is shown that upon injection of the beam into the vacuum chamber, part of the electrons in the front part of the beam is electrostatically self-accelerated. Upon the injection of the beam into a gas, which is thereby ionized, an electric field is formed which is strong enough to accelerate the plasma ions to energies significantly greater than the energy of the electron beam.
