Abstract : An ultralow-noise, medium-power traveling-wave tube was successfully built. The noise figure achieved was below 7.0 db, the power output 1-watt across the full S-band octave. A unique dual-helix approach was used. An electron gun for high-current-density operation was developed and a velocity taper on the output helix increased the power output. (Author)
