(a) Wavefront of the x-ray beam, (b) Measured intensity of the beam. (c) Intensity of the focal spot at best focus. (d) Vertical lineout (red) and (e) horizontal lineout (blue) through focus, compared with the theoretical ideal focus (dashed) when no abberations would be present. The peak intensity is 3.9 1019 W/cm2 for the 3 mJ beam energy and 60 fs pulse length that was used in the experiment.
