Paper Abstract

The bandwidth of a gyro-TWT has been broadened by partially filling the interaction circuit with dielectric to reduce its dispersion. Initial hot tests of the X-band frequency, proof-of- principle experiment demonstrated zero-drive stability and achieved a peak output power of 55 kW with 11% efficiency, 27 dB saturated gain, and an unprecedented constant-drive bandwidth of 11% for a 100 kV, 5A, (alpha) equals (upsilon) (perpendicular)/(upsilon) z equals 0.6 electron beam. As predicted by simulation studies, the amplifier's performance can be further enhanced with improved beam quality.
