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

Abstract

Detailed experimental data on an S-band high-power traveling-wave amplifier with a variable-pitch helix is presented with particular emphasis on the efficiency enhancement achieved across the frequency band. Efficiency improvement factors of from 1.4 to 2 to 1 are demonstrated. The gain is also enhanced over the entire frequency band of operation. Experimental data on a new elliptic cavity coupler for use with a helical circuit is shown. Low VSWR and insertion loss over a broad frequency band are indicated. The design of a magnetron injection gun for use with a high-power amplifier is outlined. Additional details on the noise transport analyses and beam-plasma interaction theory are given.
