Resonator systems for klystrons of millimeter and submillimeter wave bands

Resumo

Design problems of resonator systems for klystrons of millimeter and submillimeter wave bands are considered. It has been shown that, for efficient interaction of the resonator’s field and the electron beam in such devices, it is necessary to use resonators with high wave impedance. A quality factor, which allows one to compare resonators having different shapes, has been introduced. Different means of increasing the resonator’s wave impedance and circuits coupling resonators to input and output transmission lines have been investigated.
