Abstract :
Summary form only given. The Naval Research Laboratory is currently investigating gyroklystron amplifiers as high power, moderate bandwidth sources for millimeter wave radars. A four cavity W-band gyroklystron amplifier experiment is now underway at NRL. The gyroklystron has produced 55.5 kW peak output power and 23.5% electronic efficiency in the TE/sub 01/ mode for a 56 kV, 4.2 A electron beam. The -3 dB bandwidth is greater than 400 MHz. The small signal and saturated gains are 36 dB and 28 dB, respectively. A time dependent version of the non-linear code MAGYKL was developed to design the interaction circuit.
