INVESTIGATION OF LINEAR BEAM AND NEW CONCEPTS OF MICROWAVE POWER GENERATION.
Abstract
Results are presented of basic studies of the interaction of magnetically focused electron beams with electromagnetic circuits, of basic electromagnetic interaction circuits, of electron beam phenomena, of an electron-beam plasma amplifier, and of laser-stimulated electron emission. The feasibility of using biased electron beams to control phase shift in linear beam tubes is demonstrated. A study of transmission-line equivalent circuits for periodic microwave circuits is reported. Experiments were conducted on immersed-flow electron beams, and studies made of the effects of axially varying magnetic fields on beam properties. Basic probe measurements of electron densities and effective electron temperatures were made on an argon plasma identical to that used for the amplifier. The problem of coupling of microwave signals to beam plasma amplifiers is discussed. Two applications of the laserinduced electron beam are considered: (1) the measurement of the beam-loading admittance, and (2) a new program involving active interaction in which a r-f signal is propagated by the beam.
