Abstract:
1. A diffraction condition simulation device for calculating a reciprocal lattice to a crystal sample and displaying, on a computer screen, Bragg reflection conditions of X rays or particle beams caused by the crystal sample, the diffraction condition simulation device comprising: means for inputting and storing intrinsic crystal information; means for inputting non-intrinsic sample information to determine an orientation of a simulated crystal sample; means for calculating coordinates of all reciprocal lattice points within a limiting sphere of the simulated crystal sample using the intrinsic crystal information and the non-intrinsic sample information; means for displaying, on the computer screen, a cross-section of the limiting sphere which intersects with a diffraction plane, and all reciprocal lattice points contained within the cross-section; and means for adjusting an orientation of the simulated crystal sample, wherein the displayed reciprocal lattice points rotate with a rotation of the simulated crystal sample such that previously calculated reciprocal lattice points are placed and displayed on the diffraction plane continuously during rotation.
