Abstract :
8-mm and 3-mm high-power tubes have been developed. Two 8-mm-wavelength systems are examined: (1) a medium-power (tens of kilowatts) TWT (traveling wave tube) chain using PPM focusing and a low-gain ´see-through´ final stage and (2) a three-beam 50-W CW (continuous-wave) klystron. In addition, a 2-kW CW TWT was developed for industrial heating. For higher powers an orotron-TWT (3-MW peak, 3-kW average power) has been developed. AT 3-mm wavelength, a pulsed klystron with 1.5-kW power output and 300-MHz bandwidth has been developed, and a 25-W CW TWT with an 800-MHz bandwidth was produced. For 36-1500 GHz, multiple-beam oscillator BWOs (backward wave tubes) with ribbon like beams which produce 40 to 2 mW of power have been developed.<>
