Abstract : This contract calls for design, development, fabrication, and test of a fast warm-up Crystal Oscillator operating at 5 MHz and 10.05+ MHz. This first status report indicates that from the test results of the oscillators developed so far, further reductions of inner oven and oscillator assembly MASS is required. In addition, an approved method of coupling heat into the crystal blank will be worked upon. In order to reduce mass, redesign of the electronic circuitry from discrete circuits to IC and Hybrid circuits is necessary. A new configuration is shown in the report. The key innovation of the design is to put the heater and temperature sensing devices on a ceramic disk of approximately 1-in. in diameter. A new hybrid approach will permit the fastest warm-up ovenized oscillator of its kind and will out-perform the present model in reliability and quality. (Author)
