Development and validation of a time-dependent large-signal simulation code for gyroklystron amplifier

A time-dependent self-consistent large-signal simulation code for gyroklystron is developed and the key technologies involved are introduced. To validate the code, a Ka-Band gyroklystron amplifier is simulated and the effects of time step and space step are observed, which lead up to a coarse criterion about the choice of appropriate time step and space step so as to take consideration of both computation efficiency and accuracy. At the end, the simulated performance of the gyroklystron is proved to be consistent with the designed performance indexes.
