THEORETICAL AND EXPERIMENTAL INVESTIGATION OF LARGE-SIGNAL TRAVELING-WAVE TUBES

Abstract

Additional one-dimensional calculations on the relativistic traveling-wave tube are presented and the analysis is extended to cover the relativistic klystron. Significant increases in TWA efficiency are noted at high voltages and the longitudinal space-charge debunching forces are reduced in effectiveness. The relativistic klystron behaves according to a ballistic theory due to the reduced space-charge debunching. Experimental data is presented on a variable-pitch helix traveling-wave tube indicating a significant improvement in efficiency. The gain is also improved and the voltage for maximum small-signal gain is nearly the optimum for highest power output. Initial calculations on a microperveance one electron gun are made using the Poisson cell and trajectory calculator. An analysis of noise transport in linear beam devices is presented and a method for solving the a-c transport equation in a two-dimensional space-charge limited diode is outlined. (Author)
