INVESTIGATION OF ELECTRONIC INTERACTION WITH OPTICAL RESONATORS FOR MICROWAVE GENERATION AND AMPLIFICATION.
Abstract
Additional experimental results with model 2 of the monotron oscillator are described. Oscillations were observed on resonances ranging from the TE sub 6,1,1 at 40.7 GHz to the TE sub 10,1,1 at 76 GHz. Peak power outputs of up to 25 W (not including a 3 dB factor for thermistor efficiency and insertion loss of waveguide components) have been measured. Some difficulty was encountered with a bad connection between the aluminum collector film and its kovar support. The tube was disassembled; a stainless steel mesh was installed as a beam collector, and the tube was reassembled. Detailed measurements of the rf output pulse shape were made. A rise time in the range of 5 to 10 nsec was observed. The possibility of constructing an oscillator for 337-micron wavelength (890 GHz) is investigated. Dielectric loading of the TE sub n,1,1 cavity with a thin film of dielectric on the cylindrical wall of the cavity appears to be a good approach for the circuit of such an oscillator. (Author)
