Paper Abstract

We present the development of a phase compensator for wavefront control of X-rays. The optical device is a 150 mm-long total reflection mirror, the shape of which can be curved by adjusting the bias voltages of 36 piezoelectric ceramic plates attached to the mirror. The mirror surface was smoothed and made flat by elastic emission machining. To achieve a high degree of the accuracy in the controllability of a curved line, a Fizeau interferometer is placed in front of the mirror surface to monitor its shape in the experiment. We will apply this device to the optical system for the realization of sub-10-nm hard X-ray focusing.
