The report is concerned with the systematic investigation of various cleaning and processing techniques which are used to assemble high precision single sideband SSB quartz resonators. The final requirement is to be able to produce crystal units which will meet a strict aging requirement of 2 x 10 to the minus 10th powerweek, when measured at the upper turning point of the crystal unit after a stabilization period of 4 weeks. The specific aspects of resonator fabrication that was investigated during the study are several wet-cleaning processes for preparing quartz surfaces, the sputter-ion cleaning of quartz and the composition profiles and impurities associated with both the quartz surface and the copper electrodes.
