MULTIMEGAWATT BROADBAND MICROWAVE TUBES
Abstract
The centipede circuit was adapted for use on the electron stick in such a manner that the amplitude and phase of the growing wave along the beam- circuit interaction length could be measured. The results of this study will be of utmost value in optimizing the many parameters affecting the beam-circuit interaction. Current results of theory and experiment are presented. Tests on the electron stick for the suppression of parasitic oscillations were conducted: By covering the entire stick with a thin sheet of directionally resistive mylar, oscillations were removed, up to 30 kV. Two other sources of instability were found and removed: feedback oscillations and monotron oscillations. Work on calibration of external load and saturated-beam measurements is described. Studies on space-charge waves in an accelerated parallelflow electron beam in a constant magnetic field were continued. The major emphasis this period was on the analysis of the second-order differential system; a discussion of the solutions for certain conditions is presented. Preliminary work on beam-plasma studies is described. The properties of microwave acoustic wave transducers were investigated in order to improve their conversion efficiency and bandwidth.
