Abstract

We present the design results for our second harmonic coaxial gyroklystron tubes, which are expected to produce /spl sim/80 MW of peak power at 17.14 GHz in 1 /spl mu/s pulses. The beam voltage and current are 470 kV and 540 A, respectively, and the applied magnetic field is about 0.5 T. The input cavity operates near the cyclotron frequency at 8.57 GHz; all other cavities operate near the second harmonic at 17.14 GHz. The expected interaction efficiency is 32-37% and the gain is 47-60 dB, for 3 and 4 cavity tubes, respectively.
