Abstract : Many electronic devices containing quartz crystals operate in an environment exposed to radiation, and it is important therefore to investigate the effects of radiation on quartz crystals. In the present work we show that the technique of thermoluminescence TL can serve as a good tool for such an investigation. We report on TL measured in the temperature range of 15 - 300 K. The measurements have been carried out separately on the various growth sectors (namely +X, -X, +Z, -Z) of Y plates cut from a Y grown bar of unswept Electronic Grade Synthetic Quartz. The well resolved glow peaks at 72 K, 80 K, 87 K and 104 K were observed for the first time in the present work. We suggest that the glow peaks appearing only in +X growth sector samples (namely 135 K, 162 K, 178 K) after pre-irradiations at room temperature (RT) by x-rays (white radiation, 50 KV, 17 ma), might be related to (Ale+)o centers. The glow peaks above 104 K in the +Z sector samples are completely different from those observed in +X sector samples.
