摘要：

The RF structure of W-band TE01 mode gyro-klystron amplifier was modeled, analyzed on the basis of pattern matching theory and the nonlinear theory of beam-wave interaction in the gyro-klystron amplifier, and simulated. Based on the calculated results, a four-cavity particle simulation model of the RF system was formulated and used to simulate with software MAGIC and optimize the beam-wave interaction involved. The impact of the key variables, including the drift length, current and voltage of electron beam, and ratio of traverse/longitudinal speeds, on the output power, efficiency and gain was investigated. The simulated results show that the newly-designed W-band gyro-klystron amplifier is capable of providing an output power of 362 kW with an efficiency of 32% and a gain of 37 dB under the conditions: a working voltage of 75 kV, a current of 15 A, a magnetic field of 3.29 T, an input power of 72 W, and a traverse/longitudinal speed- ratio of 1.5. ©, 2015, Science Press.
