Low-frequency beam vibration study. Four subsequent dark- and flatfield-corrected images of the unfocused direct beam collected at the sample position (a) on the old set-up with the Kohzu monochromator and (b) on the new set-up with the channel-cut monochromator. (c) Plotting of the normalized intensity changes along the full 50 subsequent measurements on the old set-up is in red, while on the new set-up it is in blue. |
