Dynamics of the modulated electron beam in the inhomogeneous plasma barrier: one-dimentional simulation using PIC method

摘要

Evolution of the modulated electron beam moving through the plasma barrier was studied via computer simulation using PIC method. Inhomogeneous plasma barrier with parameters corresponding to experimental conditions [1-2] was studied. Dependencies of the maximal signal amplitude and coordinate of this maximum at the modulation frequency upon the initial beam modulation depth were obtained. Simulation results were compared with experimental results and outcomes of the previous simulations.
