Abstract

The spatial distribution of defects and impurities in a variety of high-purity silica glass manufactured by different methods are studied. The defects investigated include those found in the as-manufactured glass (oxygen vacancy and peroxy linkage), as well as those induced by ionizing radiation or ultraviolet light (E' center and oxygen hole centers). A significant difference is observed in the distribution between silica manufactured by different methods. Furthermore, the defects induced by ionizing radiation or ultraviolet light have a spatial distribution relative to the geometry of the as-manufactured boule, suggesting that these defects arise primarily from the activation of preexisting precursors.
