Feng-Yuan Zhang,Wenbin Liu,Zhihao Jin,Zhiqiang Zhang,Zhaochuan Zhang,Kedong Zhao,Jin Xu,Yanyu Wei,Feng Lan,Ziqiang Yang +9 more
TL;DR: In this article , an extended interaction klystron (EIK) working at the frequency of 340 GHz was designed, and the characteristic impedance, coupling coefficient, and normalized electron conductance of the cold cavities were analyzed and optimized.
Journal ArticleDOI
Analysis of the circular-arc-shaped helical groove slow-wave structure
TL;DR: In this article, the dispersion curves and coupling impedances of the fundamental wave and some harmonics are calculated and the influences of various circuit dimensions are discussed, showing that the bandwidth can be improved by increasing the arc angle or decreasing the pitch of the structure; a 50% bandwidth is achieved by deviating the phase velocity within ±5%.
