Online operation of the X-ray beam monitoring system. (a) The image of the small knife edge inserted into the X-ray beam recorded with the XBM during online X-ray beam stabilization. The individual pixel response of the camera is corrected for with a gain map. The black box indicates the region of interest for X-ray flux determination while the green and red boxes indicate the regions of interest for the error function fit along the vertical and horizontal knife edges. Panels (b) and (c) depict the measured data as circles and fits as solid lines with the color corresponding to the respective regions of interest.
