Abstract:

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.
