Open publisher page 1 citations

Abstract

2.5-dimensional(2.5-D) particle-in-cell simulation code MAGIC and 3-D electromagnetic simulation code HFSS were used to investigate the helix traveling-wave tube(TWT) with positively-negatively tapered structure for efficiency enhancement.Some key parameters to efficiency were analyzed,including high-frequency parameter,non-synchronous parameter,gain parameter and electron phase.A positively-negatively tapered helix TWT were designed and fabricated.The results show that the measured efficiency of the tapered TWT reaches 29%,while that of the non-tapered TWT is 19%.It shows the average relative error of the simulation method is about 5%.
