Abstract

Description

A method and apparatus to simultaneously measure the diffraction resolution and mosaic spread of macromolecular crystals, are described. The method includes minimizing contributions of an x-ray beam to any reflection angular widths in the crystal, rapidly measuring multi reflection profiles in the crystal over a wide resolution range, evaluating and deconvoluting the Lorentz effect and beam contributions, and determining the direction in which the crystal is most perfect.
