摘要：
Simulation of gyrotrons using the particle-in-cell method predominantly requires 3D calculations. At large oversize factors of the interaction space, it leads to lengthy calculation times. We show that under certain conditions, the dimensionality of the problem can be reduced and 2.5D PIC simulations can be applied. Using the example of a 170 GHz gyrotron with TE28,12 operating mode, we study the influence of the external signal on the noise level in the output radiation under conditions of fluctuations of the accelerating voltage.
