VACUUM TUBE RESEARCH PROJECT.
Abstract
Work to date on the plasma amplifier and measurement of electron density by microwave methods is summarized. The equations which govern the large signal behavior of beam-type crossed field tubes was formulated. These equations are being programmed for numerical solution on the IBM 704 digital computer. A new mode of wave propagation on finite diameter magnetically focused electron beams was found in the course of studying noise propagation near the potential minimum of a diode. A few of the important properties were explored theoretically. Propagation is not dependent on the electron drift velocity and a preliminary experimental verification was obtained using a plasma-filled waveguide. (Author)
