Paper Abstract

A gyro-TWT is often plagued by absolute instabilities in lower order modes and even in the operating mode itself. These problems will be avoided by performing an experiment in the lowest order mode in cylindrical waveguide ( TE11 ) and using a low α beam to excite a wave with large kn. A gyroresonant wiggler will partially transform the axial velocity of a high quality Pierce beam into transverse velocity. A 100 keV, 5 A, α = 0.5 beam will generate 9 GHz rf in a 3 kG magnetic field. Magnetic tapering will be used to enchance the efficiency. The theoretical gain is predicted to be 60 dB with a bandwidth over 20%.
