Abstract

Design of a three-cavity Ka-band MW-level gyroklystron operating in the TE₀₂ mode in the output cavity while the input cavity and buncher are operating with the TE₀₁ mode is presented. The optimised design of the magnetron injection gun (MIG) and interaction circuit has been completed by particle-in-cell simulation and analytically using a MATLAB code. The simulations show the gyroklystron can deliver an output power of more than 1.5 MW with a gain of > 35 dB at 36 GHz. The achieved efficiency exceeds 40% when driven by a 95 kV, 45 A beam. The optimised MIG has a transverse velocity spread of < 3% when the velocity ratio is around 1.3.
