摘要
通过注波互作用机理的定性讨论得到了过渡段螺距合理渐变能改善螺旋线行波管效率的初步结论,而由过渡段螺距改变前后的螺旋线行波管色散方程和工作方程的理论分析得出的数值计算结果与初步结论相一致,并得出了过渡段螺距恰当的渐变方式对改善相速跳变螺旋线行波管的边频效率起很大作用的重要结论。得出的结论对螺旋线慢波系统设计工作的进一步开展指明了一个方向。
After getting the initial conclusion by qualitative discussions of the operation mechanism of the beam and the wave that the proper modes of gradual changes of transitional helix pitches can improve the electronic efficiency of helix TWTs, the analyses and summaries of the dispersion equation and the calculating results of numerical values of the working equations of some helix TWT by changing the helix pitches of transitions consist with the initial conclusion, and conclude that the proper modes of gradual changes of transitional helix pitches can improve the electronic efficiency of the bound of the bandwidth of helix TWTs effectively . The result can point out a way for the further developing of design of helix slow wave structures.
