Modelling of electron stream discharge

Planar many-particle model [1–4] is used to simulate the gas discharge initiated by high current, middle energy, hot electron stream (Ie ≈ 10kA, εe ≈ 10keV, δe ≈ 1keV) in atomar and molecular gases (H, Ar, N2, p ≤ 133Pa). Such electron stream has been observed during the relativistic electron beam-plasma interaction at the experimental REBEX facility [5–7]. The stream electrons are injected through the entrance foil into the drift tube fulfilled by neutral gas and leaves the target body via exit foil which serves as the reference zero potential for the system. Current is closed via external RC circuit without any external voltage/current source.
