X-ray beam monitoring and wavelength calibration using four-beam diffraction. [PDF]
J Synchrotron Radiat, 2022 Rigorous dynamical theory calculations show that four-beam diffraction (4BD) can be activated only by a unique photon energy and a unique incidence direction. Thus, 4BD may be used to precisely calibrate X-ray photon energies and beam positions. Based on
