Abstract : The requirements and previous literature which indicates that Q of 3 x ten to the 6th is possible at a frequency of 5 mc. To reach the desired Q, it is indicated that a plano-convex blank is necessary, together with evacuation of the unit in a glass holder. Maintenance of angle of orientation to =15 seconds of the Z-Z' will be necessary to achieve the desired change in frequency. Proposed improvement to the frequency standard and measurements system are detailed, as well as a description of an oven to be used for aging measurements. The complete prototype crystal unit design specification is included. (Author)
