An analysis of the parametric excitation of fast and slow space-charge waves in a cylindrical metallic waveguide filled with relativistic beam electrons is presented. The pump wave in the laboratory reference frame consists of a static, spatially periodic axial electric field. Formulas are derived for the temporal growth rate and frequency of the backscattered fast space-charge wave in both the laboratory and beam frames. The effects of a uniform axial magnetic field of arbitrary magnitude on the amplitude gain and frequency enhancement are studied.
