Particle-in-cell (PIC) simulations of beam instabilities in gyrotrons
Extensive simulations are performed to investigate effects of electron cyclotron instabilities on the gyrotron beam quality, using 2-dimensional axisymmetric particle-in-cell (PIC) codes. Both electrostatic and electromagnetic models, as well as realistic geometries of the gyrotron are considered. It is found that a large beam density can lead to an electrostatic-instability-induced energy spread which substantially degrades the gyrotron efficiency.
