Abstract

Report demonstrates the results of coherent power summation from two nanosecond-width relativistic Ka-band BWOs with the peak power above 200 MW in each channel. A peculiar feature of the experiment was in supplying the explosive electron emission cathodes with ultimate-stable split voltage pulse from an all-solid-state SOS modulator. Enhanced rate of the voltage rise provided stable emission of electron beams and minimized standard deviation of the microwaves phases between channels in the time scale down to 0.5 ps.
