Optimization and theoretical performance of an adaptive x-ray mirror

The performance of an adaptive mirror strongly depends on the quality of the overall mirror optimization and on the model on which the control algorithm is based. Fundamental parameters entering the mirror design are: mirror function, source and beam parameters, response time, actuator positions and forces. In a case of a wiggler source, we show that it is possible to decrease the thermal deformation generated by 4 kW absorbed power by a segmented mirror of one meter length from 600 μrad to a few μrad. The discussion is based on detailed mechanical analysis and on ray‐tracing simulation.
