| 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 ... |

| A study was made of the comparative aging rates of glass vs. metal enclosed units. The intent was to establish, if possible, the contributing factors related to crystal unit aging. Control groups were divided so that identifical groups were enclosed in both glass and metal, using various types of mounting clips and bonding cements. The units were aged at 85C. All units were 30mc units. Because of the complexity involved ... |

| The report details results of fabrication of units prepared during the quarter, and indicates problems have been encountered in maintaining desired angles of orientation through the contouring operation. 'Q' in excess of 500,000 has been achieved with units finished with a 305 abrasive and plated with an evaporated aluminum film. Successful methods of achieving a mechanically strong bond using cement are also reported. Photographs and details of the aging equipment ... |

| 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 ... |

| Efforts concern establishment of a facility for the manufacture of crystal-units CR-(XM28)/U utilizing the HC-27/U all glass holder. Comparisons of results achieved using goldplated electrodes with those achieved using aluminum, are made. The same improvement in control of frequency change is noted when the film is annealed prior to sealing in glass. Final details of the limited production equipment were worked out and the equipment is described. A method for ... |

| Efforts were continued on the manufacture of crystal unit CR-(XM-28). Attempts to obtain con sistently satisfactory seals of the HC-27/U type holder were unsuccessful. A design for a new holding fixture is shown, and a commercially available sealing machine is reported. Results indicate that the unglazed base is superior to the glazed in obtaining good seals of the glass parts. A method of cleaning Kovar is reported on, as well ... |
