The preproduction crystals to be fabricated from natural quartz were completed. This consists of seven crystals each at 5MC, 10MC and 20MC. Some preproduction crystals were fabricated from cultured quartz but design problems with respect to temperature characteristics were encountered. The production crystal designs for the units to be fabricated from natural quartz were finalized on the basis of the engineering samples. These designs are included in this report. Author
