Zusammenfassung:This work deals with calculation of electron beam generated in a plasma focus device. The Vlasov-Maxwell equations of the charged particles are solved using the forward semi-Lagrangian method. The traces of the electrons are computed. It is shown that electron beams are emitted by strong electric field generated by compression, turbulent, and disruption phenomena in the electrons motion. The energy spectrum of emission shows dependence on pressure and pinch current.
