Jmulti — three-wave X-ray diffraction simulation software

X-ray diffraction methods are used to obtain structure information of most of materials. The analysis of the energy and azimuthal dependences of Bragg reflections is one of such methods. But if an intensity of Bragg reflections is low, the shape of curves is often distorted due to three-wave reflections, which complicates the interpretation of the results. This can be avoided by preliminary analysis of conditions for the occurrence of three-wave reflections. This work is devoted to the Jmulti program, which calculates the azimuthal-energy maps of three-wave reflections and allows to select the optimal conditions for measuring the azimuthal and energy dependences of Bragg reflections.
