Abstract :
The UCD peniotron has been designed for optimum device efficiency and output power in second-harmonic operation at a 34 GHz fundamental-mode resonance. Key to the design is interaction with the axis-encircling electron beam. The UCD device incorporates over-coupling of the cavity to achieve the desired increased device efficiency. The predicted efficiency and power have been calculated from our large signal code.
