Abstract

Abstract

The double taper helix slow wave structure is one of the most widely used slow wave structures in space TWT. The effects of parameters such as length and pitch of double-taper helix slow wave structure on the electron efficiency and gain of TWT are investigated using the Christine large signal code. The result shows that the gain and the electron efficiency of TWT are in direct proportion to the length of each part of the slow wave structure, and the length of the signal input section has largest influence on the gain; the electron efficiency of the TWT is most sensitive to the pitch of the section where the phase velocity increases. Furthermore, the slow wave structure is optimized preliminarily by simultaneously increasing the length of the signal input section, reducing the pitch of th
