a. Diffraction image showing the belt background on the XRD CCD detector with the maximum absorption of Kapton highlighted in red and the minimum in blue. b. A simplified geometry of the conveyor belt and the shadow it casts on the CCD. c. Illustrations of the parameters used in the Kapton absorption correction from left to right: on beam axis view, zoomed in beam axis view, and top view.
