Abstract (englisch):
An optimized second harmonic cavity for a 170 GHz 1.3MW fusion gyrotron is presented. The suppression of the competing modes at fundamental frequency is achieved solely due to a specific design of the coaxial cavity with corrugated inner conductor and does not require e.g. the injection of an external signal. The design is verified by self-consistent multimode simulations. The results show an excellent suppression of the competing fundamental modes.
