Sumario: | In Klystron amplifiers, monotron oscillations
may cause unacceptable beam instabilities. For facilitating fast and accurate analysis of such processes, rather
than performing time-consuming particle-in-cell simulations, the theory of the monotron oscillations has been
further developed for the small- and large-signal regimes
and implemented into the klystron computer code KlyC.
This development includes full considerations of the spacecharge effects, relativistic effects and can operate with
arbitrary field distributions of the resonant mode. The
effectiveness of these methods, have been demonstrated
through benchmarking against PIC codes and has shown
good (at 1% level) agreement, while KlyC computation
time is significantly (at least 100 times) faster than in the
PIC simulations. |
