Abstract
The formation in the REBEX experimental device of a Virtual Cathode (VC) by a Relativistic Electron Beam (REB) propagating through the end foil into the vacuum region was studied. The properties of the beam (homogeneity and angular spread of particle velocities) and of the originating magnetic fields (e.g. equipotentials of the VC, the internal azimuthal magnetic field) were determined numerically using the 2d relativistic electromagnetic current-line code `POISSON 2`. The dependence was calculated of the reflection coefficient of the REB scattered by the formed VC, on the total beam current, beam energy, external magnetic field and on the length of vacuum drift tube. The results obtained are useful for an additional plasma heating mechanism via the two-stream instability generated by the oscillating REB. (author) 1 tab., 15 figs., 7 refs.
