Figure 5
Dynamic measurement of the X-ray beam size with (blue curve) and without (black curve) manual compensation of voltages to reduce the effect of piezo creep. Jumps in the blue curve correspond to when small voltage corrections were applied to the mirror. With this simple correction scheme, the X-ray beam reaches 95% of its final size in less than 2 s, 98% within 3 s and 99% within 7 s. This clearly demonstrates that the size of the X-ray beam can be rapidly controlled and stabilized in just a few seconds.
