Abstract:

A triodecavity oscillator capable of 50 watts of pulse power output and tunable with one knob tuning over a frequency of 9.2 to 9.6 Gc was designed and 10 of the units were built and evaluated for initial performance. Desirable features of the oscillator are its small size, light weight approximately 1 oz, and its low power consumption. The filament power is approximately 1.3 watts and the average plate power is approximately 0.75 watts e sub b 1500 V, i sub p 800 ma, duty 0.05. Twelve tube designs totaling approximately 215 tubes were made and evaluated during the program. The basic problem encountered was insufficient peak emission J approximately 40 Asquare cm in tubes at a reasonable cathode temperature. Triodes of the final design, type Y-1249-N, have adequate emission for initial oscillator performance within specification limits. However, the probability of meeting the 500-hour life before the output drops 3 db is undetermined since the contract time and funding limitations did not allow for the additional life tests. Author
