STUDY OF TRANSVERSE WAVE INTERACTIONS.
Abstract
The purpose of the project is to evaluate analytically and experimentally the interaction of waves in a wave guide with waves on a rotating electron beam. The methods of analysis include use of a general coupled-mode theory, a ballistic computer program, and an experimental evaluation. Theoretical work has centered on the transverse bunching effect. It was found that when the absolute value of the bunching parameter zeta, which is related to the magnitudes of the beam modes, is greater than one, electrons pass each other. From criteria based on consideration of the ordinary backward-wave oscillator, it appears that power saturation occurs when electrons begin to pass each other. The construction of the new tube is finished and it is being tested. Initial power measurements indicate that the power output is lower than that obtained from the previous tube. It is expected that the power output will be increased. (Author)
