Paper Abstract

The design of a stable gyro-TWT amplifier that can generate extremely high power at cyclotron harmonic frequencies is presented. To prevent competing backward wave modes from oscillating, an amplifier with a multistage structure is used. Although the interaction strength in a harmonic gyro-TWT is strongest if an axis-encircling electron beam is employed, a more common MIG beam has been used in this design study to make it more practical. Using a 100 kV, 25 A MIG beam, a peak output power of 533 kW, peak efficiency of 21.3% and a saturated bandwidth of 7.4% have been predicted by a nonlinear self-consistent analysis for a three-stage second-harmonic stable gyro-TWT amplifier.
