Design of a heavily loaded output cavity for the one-microsecond, one kilojoule per-pulse L-band relativistic klystron
- Los Alamos National Lab., NM (United States)
The development of a high-current relativistic klystron amplifier (RKA) is continuing at Los Alamos. The goal is to produce 1 kJ per pulse, with a one-microsecond pulsewidth, and a peak power of 1 GW. The three cavity tube has already produced pulses with more than 150 J and over 450 MW peak power. A number of very low Q output cavity structures for the RKA have been successfully modeled using HFSS (High Frequency Structure Simulator). A low cavity shunt impedance is necessary to efficiently couple energy out of the low-impedance modulated beam. The latest cavity design is presently being conditioned up to full power operation. Current experimental results and comparisons between HFSS predictions and measured cavity responses are presented.
