Abstract:

A combined theoretical and experimental program to investigate several fast wave interaction mechanisms between microwave radiation and a plasma or electron gas in a uniform magnetic field is described. An average electron model is presented this model is applicable to the situation of electrons in a rectangular waveguide. The model predicts the predominance of the relativistically dependent mechanism as the phase velocity of the wave approaches infinity, e.g., the situation at waveguide cutoff. Measurements of the absorption of microwave power by electrons in a rectangular waveguide are presented. These data show the relativistic shift of the absorption curve with increasing transverse electron energy. Both from technical and economic considerations, an amplifier device, based on these fast wave mechanisms does not appear to be feasible at this time. To realize a practical amplifier a reliable and economical method of producing a highly anisotropic electron beam must be developed.
