Abstract
Deformable mirrors (DMs) have been successfully used in astronomical adaptive optics at visible and near-infrared wavelengths, greatly reducing atmospheric-induced aberrations. Building upon the extensive techniques and methods developed for these applications, we propose to extend this capability to the soft and hard x-ray regime in order to take full advantage of the beam quality characteristic of new facilities such as the National Synchrotron Light Source (NSLS-II), and the Linac Coherent Light Source (LCLS). Achieving this goal challenges both current mirror manufacturing techniques and wavefront propagation modeling. Lawrence Livermore National Laboratory (LLNL), in collaboration with Northrop Grumman AOA Xinetics Inc., is currently developing an x-ray deformable mirror to correct for wave-front aberrations introduced along the beam path of a typical x-ray beamline. To model the expected performance of such a mirror, we have developed a simulation based on the wavefront propagation code PROPER. We will present the current implementation of the software, which models actuation of a deformable mirror and evaluates its effect on wavefront correction.
