FIG. 1.

Sketch of the experiment showing the loaded specimen, the 2D detector, the incident x-ray beam, and the diffracted beam at Bragg’s angle . is the angle between the specimen surface normal and the diffracting plane normal, the rotation angle of the specimen around its surface normal, is the direction of load application, is the rotation angle around the detector surface normal. The Beamstop position is shown on the detector. is the incident beam angle .
