5 MC SINGLE SIDEBAND CRYSTALS.
Abstract
The project is intended to develop a non-controlled crystal having a precision of frequency in the order of 5 pp 10 to the 6th power, a stability of 1 pp 10 to the 8th power per week - or better - - and a Q in excess of 500,000. Prior to this period, it was demonstrated that engineering samples could meet the requirements. The single obstacle which prevented submission at that time was that the exact aging test could not be performed successfully. During this interval, equipment modifications were made and several aging tests were performed on gold - plated units. The various aging test attempts are reviewed, and problems are discussed. The report includes a number of tables which clearly show the difference in frequency between the upper and lower turnover points as compared to the ZZ' angle. (Author)
