  • Abstract
    The design and cold test of a novel over-moded folded-waveguide 94 GHz TWT is discussed with operation in the rectangular TM31 mode. Lower order modes are suppressed with dielectric loading. With plans for fabrication, simulations show 31 dB of gain and 300 W peak output power. Cold test results for a 9-cavity structure are forthcoming.
