Abstract :
In this paper we consider the preliminary designs of three-cavity microwave circuits for coaxial gyroklystrons. These tubes are predicted to produce over 100 MW of power in 1 μs pulses in X- and Ku-band for linear collider applications with efficiencies exceeding 40% and gains above 50 dB. In particular, we examine the effect of first and second harmonic buncher cavities on the efficiency and gain of both first and second harmonic microwave circuits. We also examine the necessary conditions to contain the axial field profile of overmoded buncher and output cavities. Performance is contrasted with current two-cavity designs
