Abstract:
Results of 3D numerical modeling of two-mode two-gap multi-channel resonator loaded to the inductive rods are presented. Such a resonator can be used in a buncher of multi-beam klystron. It is able to become excited simultaneously at two resonance frequencies (2,45 and 4,9 GHz) that correspond to in-phase and anti-phase oscillation types. Ways of decreasing an irregularity of HF-electrical field strength of such a resonator by a change of a number of beam channels and its mutual orientation are found.
