Experiment on Radial Beam Angular Log-periodic Strip-line Traveling Wave Tube

In this paper, the hot testing experiments for radial beam angular log-periodic strip-line (ALSL) traveling wave tubes (TWTs) are investigated. The whole tube was assembled and welded for the planar strip-line slow wave structure (SWS) and the corresponding experiments were performed. Electron gun emission current 52mA, collector current 36mA, transmission rate of 69%. Experimental maximum output gain of 4.4dB, and the overall gain trend is consistent with the simulation results. The working capability of the radial beam TWT was verified rationally in the experiments.
