[en] The potential of using the FX25 relativistic electron beam generator to produce a multikilovolt, 1015 to 1017 cm-3 density plasma is discussed. An initial design of an experiment to investigate the effects of ionization gradients, hydrodynamic gradients, anode foil scattering, external magnetic field strength, and beam self-magnetic field strength on the collective interaction is provided. It is concluded that a plasma energy density of 1020 to 1021 eV/cm3 may be achievable with the FX25 generator
