Abstract :
The design for a high performance, 33.2 GHz three-cavity gyroklystron has been completed. The design modifies Varian´s pioneering 28 GHz gyroklystron in order to suppress oscillation and yield higher gain and efficiency. Modifications include an additional buncher cavity, lower beam a, and a slight increase in frequency. Self-consistent simulation for an axial velocity spread of 7% and α=1.5 predicts an output power of 250 kW with a saturated gain of 52 dB and an efficiency of 39%. An investigation of penultimate cavity detuning showed no improvement in efficiency for the above velocity spread. A synchronously tuned gyroklystron is currently being constructed.
