Abstract

A method for evaluating the thermal dimensional stability and homogeneity of beryllium mirrors is described. Thermal dimensional instabilities are shown to be highly dependent on crystalline anisotropy. An x-ray quality control technique is discussed which can be used to predict optical performance under changes in ambient temperature.
