THEORETICAL DESIGN AND NUMERICAL SIMULATIONS OF RADIAL KLYSTRON OSCILLATOR
On a certain approximation, the generation and the oscillation of microwave in the cavity based on transit time effect for one shot microwave source are analyzed.For reasons given, we have made theoretical design and numerical simulation of radial klystron oscillator for GW level output. A peak value (average over a period) of 1.6×2GW ( f =6.0GHz) is obtained. The width of the microwave putse is 40ns under the condition of the potential pulse width of 116ns. An electron efficiency is about 12.8%.
