(a) The dynamic radius of curvature of Mirror 3, as measured by a Fizeau interferometer, with (green curve) and without (red curve) corrective voltages uniformly applied to all electrodes to compensate for piezo creep following a 1000 V impulse. Using creep compensation, we have shown for the first time that a synchrotron X-ray bimorph mirror can be bent and stabilized to <1% of any given curvature within <10 s. (b) The black line shows the measured change in curvature [the difference between the two curves in panel (a)] as a function of time, compared with the output of equation (2[link]) where applied creep-compensation voltages are converted into predicted curvature changes (blue squares).
