Figure 2
A sketch of the SAG. P and A are, respectively, the polarizer and analyser setting and analysing the polarization component (in the plane of the figure) perpendicular to the precession field B (perpendicular to the plane of the figure). The precession region has faces inclined by θ0 to the main axis and a distance L between the faces. Intensity is measured on the detector (Det) at an angle x. The angle ∊ is the deviation angle between the diffracting plane and the inclination angle θ0. |
