(Technical note no. 5) (Contract AF 61(052)264) (RADC-TDR-61-294)Unclassified report DESCRIPTORS: (*Microwave oscillators, *Cavity resonators, Design, Tests, Norway.) (Electron tubes, Electron beams, Helixes, Electric fields.) (Oscillators, Frequency modulation.) Identifiers: Dicatron, Monotron.A description is given of an experimental oscillator consisting essentially of a hollow electron beam interacting wi h the longitudinal electric field between 2 coupled concentric helices shorted at both ends, thus constituting a resonant cavity. The tube is normally operated under pulsed conditions at 950 volt and 75 ma beam current, and delivers peak output power of the order of 3 watts in the n=6 mode (3 wavelengths), which is the normal mode of operation. The oscillator can be frequency modulated much similar to a floating drift-tube klystron by applying a varying voltage to th resonator. Experimental results of power output and electronic tuning bandwidth are presented and compared with theory. (Author)
