Precision Single Sideband Crystal Units.
Abstract
ILLATORS, Manufacturing methods, Electron spectroscopy, Electron microscopy, ReliabilityThe 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 power/week, 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 have been investigated during this reporting period are several wet-cleaning processes for preparing quartz surfaces, the sputter-ion cleaning of quartz and the composition profiles and impurities associatied with both the quartz surface and the copper electrodes.
