An Investigation of Power Suck-out in Helix Traveling-wave Tubes.

Abstract

This report describes the results of an experimental investigation of power suck-out in high power single helix traveling-wave amplifiers. The objective here is to perform a variety of measurements which thoroughly and systematically characterize the phenomenon in one particular tube type. The resulting description of power suck-out provides a firm basis for a theoretical solution, and indicates design considerations which may reduce its effects. In particular, the results establish a relationship between the power holes and the output helix stop band at pi radians phase shift per helix turn, and suggest in interpretation of the interaction which causes power suck-out.
