SIMULATION INVESTIGATION OF AN IMPROVED L-BAND LADDER CATHODE MILO

摘要：

Optimization for L-band ladder cathode MILO based on an existing model is carried out. The efficiency is improved by changing the parameters of choke and SWS vanes. The resonant frequency and Q factor are obtained through numerical calculation of open cavity high frequency characteristics. Then a 2.5-dimensional electromagnetic PIC code is used for optimizing simulation. Employing an electron beam of 568 kV, 53.3 kA, a TEM mode high power microwave with output power of 5.5GW, frequency of 1.2GHz is obtained. The power conversion efficiency is 18.2％. Index terms: MILO, high power microwave, beam wave interaction efficiency, high frequency analysis of open cavity, electromagnetic PIC simulation
