I am getting asymmetric xrd peaks using synchrotron radiation while doing a scan for the LaB6 standard. What are the possible reasons for it? How can I mitigate this issue?
Dear Nilabja, some more details of your experiment are required - how do you detect your diffractogram? Theta-two theta, asymmetrical diffraction (theta fixed, two-theta scanned), reflection or transmission mode, detectors (2D-detector fixed, scanned, scanned point detector, ...) - there are many possible sources of your observation, misalignment in a scanning theta-2theta geometry would be the simplest explanantion ..., but also the radial integration of the diffracted intensities on a 2D-detector may cause such phenomena. Also the configuration of the incident beam can cause asymmetries in a synchrotron experiment (bending magnet, wiggler, undulator beams are eventually not homogeneous in their intensity distribution, etc.).
