Fluid Simulation of Klystron Output Cavities With Optimization of Electron Beam Bunching.
Final rept. Oct 98-Sep 99
ARMY RESEARCH LAB ADELPHI MD
Pagination or Media Count:
A one-dimensional fluid model for a coupled system of klystron output cavities is developed. The model is exercised for both realistic and optimized beam current modulation waveforms, and the rf conversion efficiency is calculated. An optimized second harmonic velocity modulation and associated current modulation are calculated and inputted into the cavity simulation. Optimum bunching lengths and rf conversion efficiencies are determined.
