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%
