Abstract:
Dependence of the spectral resolution of a focusing X-ray diffractor on the shape of the reflecting crystallographic planes was theoretically studied in the point source approximation. An analytical expression describing the resolution as a function of the crystal curvature in the focusing circle plane was derived. An optimum radius of the curvature ensuring the best spectral resolution was determined for a nonsymmetric diffractor scheme.
