Abstract:
The simulation technique of helical beam formation system of gyrotrons with typical axial symmetry distortion is presented. The simulation of the second harmonic magnetroninjection gun for 260 GHz band gyrotron with 0.5 mm beam axis displacement was made. It was shown that displacement of axis beam has a significant effect upon the angular distribution of pitch-factor.
Keywords:Gyrotron, electron optics, magnetron-injection gun.
