Figure 1
(a) Sketch of the defocusing due to a straight linear detector used in Bragg–Brentano geometry. At lower angles, where the focusing circle is large and the orientation of the detector is very unfavourable, large blurring of the signal results from the use of the linear detector. (b) shows the powder diffraction pattern of a LaB6 powder obtained using different parts of the linear detector. Insets show the line shape of the {100} and {510} peaks; double peaks arise from the Cu K doublet. |
