Abstract : Recent experiments on electron beam-plasma interaction have been performed using a thermally generated cesium plasma. The experimental results obtained are in excellent agreement with the theoretical predictions. These experiments show that the possibilities of using this interaction for the amplification of microwaves may, in the future, provide significant advantages over the existing devices now available. There is a possibility of obtaining high efficiencies at high-power levels. Because no circuit is used, and because it may be possible to couple to the beam in radically new ways, millimeter wavelength amplifiers and oscillators based on beam-plasma interaction look extremely promising. The problems involved in the design of such devices are discussed. (Author)
