Abstract

In order to develop a high power Ku-band gyroklystron amplifier with high gain and efficiency for driving future linear colliders, a theoretical design of a four-cavity coaxial 17.1 GHz gyroklystron amplifier has been carried out. The X-band input cavity operates at TE ₀₁₁ mode while the remaining three cavities (buncher, penultimate and output) operate at TE₀₂₁ mode, doubling the frequency of the input signal. The simulations show that both a very high efficiency of 45.6% and a gain of 71 dB can be realized using a 500 kV, 700 A electron beam with a perpendicular-to-parallel velocity ratio of 1.5 and a parallel velocity spread of 6.4%
