Abstract

The wide-band low-gain feature of a tapered smooth wall gyro-traveling wave tube (gyro-TWT) was combined with the low beam energy, low magnetic field, and high gain, though narrow band, feature of a vane loaded nontapered gyro-TWT, to propose a distributed, tapered vane loaded gyro-TWT for both high gains and wide bandwidths. The device was analyzed for the tapering of any one of the three parameters - the waveguide radius, the vane depth, and the vane angle keeping the remaining two as constant. The magnetic field was also synchronously tapered. The optimum taper and vane parameters were predicted for a large gain and bandwidth
