Abstract : Conclusions: Techniques and processes, which were successfully applied in fabricating the Preproduction Samples, are adequate for the Production Run. Successive crystal fabrication-in prior development effort and for Reproduction Samples-produced results which are substantially identical. The rejection rate is greater for the unwanted mode test than for all remaining tests combined; unwanted mode rejects range from 0% at 1.75 mc to 50% at 5 mc. Similar results are anticipated for the Production Run. (Author)
