Abstract

Sol-gel bonding, an alternate bonding technique, is proposed and demonstrated through experimentation for potentially reducing x-ray mirror distortion and cure times. The current state-of-the-art adhesives for bonding posts and mirrors are known to cause shrinkage when cured. This shrinkage causes stress at the epoxy contact point and distorts the entire mirror. This problem needs to be addressed to meet future telescope requirements. Specifically, advancements in thin segmented-optical mirrors to achieve high angular-resolution and large collecting-area in X-ray telescopes (such as the Lynx mission concept) will benefit from low stress bonding.
