Abstract :
For the first time ever, peniotron oscillations above 90 GHz (at the harmonic: f/spl ap/4f/sub c/) were observed from a peniotron designed for low power end utilizing a straight "crossed-waveguide" section as cavity. However, to obtain good performance of the tube, a low cost and highly precise circuit fabrication technique was developed where the circuit is fabricated from essentially a single block of material. Discussed are the subsequent development of high power (20-100 kW) 95 GHz peniotron amplifiers operating in a 10 vane rising sun magnetron circuit and the fabrication and cold testing of a 20 kW oscillator. Also discussed are a novel electron gun design and the design and test results of both low and high power broadband 95 GHz RF windows.<>
