Abstract
The construction of X-ray telescopes that exhibit both high resolution and a low mass to effective area ratio poses
many unique challenges. As the development of lightweight silicon X-ray mirrors approaches sub-arc-second
resolution, previously inconsequential effects and complications must be addressed. This paper will address the
structural analysis methods and experimental data that has been collected in attempts to address and resolve these
issues for silicon mirror modules. Various parameters are run through trade space using Finite Element (FE) models
and ray trace algorithms in attempts to contribute to the understanding of challenging and extremely sensitive
conditions. Results and experimental data are then used to guide the on-going development of optics modules meeting
the requirements of ambitious future X-ray missions. In this paper we discuss how the stringent distortion
requirements of a high-resolution telescope are combined with launch vibration strength requirements to design
optimized mirror modules.
