(a) Schematic of the ID23-2 KB system. The X-ray beam enters from the right-hand side of the system (vertical focusing first). (b) Photograph of the KB system as installed in the experimental hutch of ID23-2. Beam goes from right to left. The KB box has a transparent lid fitted for the photograph. Under normal operation a steel lid is in place, with an over-pressure of helium in the box and the perspex temperature fluctuation damping box surrounding the steel vessel. (c and d) Knife-edge scans of the horizontal and vertical beam, respectively. The solid line shows the raw data and the dashed line shows the derivative giving the FWHM beam sizes. |
