Abstract

We have used coherent wavefront propagation simulation (in python) to demonstrate that the current generation of bimorph deformable mirrors can be used as a pre-mirror in a grating monochromator to improve their performance and expand their range of application. We have used influence functions acquired from an existing deformable mirror to make sure the wavefront correction can be achieved in actual implementations and establish a set of specification requirements for such mirrors (number of actuators, precision, distance between the optical elements.) We also discuss the relative benefits of positioning the adaptive mirror before or after the grating, and we show that given typical beamline designs and undulator bandwidth, such a solution is viable to achieve wavefront correction on a dispersed beam and achieve photon energy high resolution to go beyond the limitations of state-of-the-art manufacturing capabilities of gratings.
