Figure 3
Usable detector width in order to limit the effect of blurring. (a) shows the usable detector offsets dmin and dmax from equations (6) and (7) for a given length of B for a fixed slit [S from equation (5)], where the area between the curves of the same colour gives the range of d values to be used. (b) shows the same, but as deduced for variable slits. Dashed lines indicate the extension of our detector. A dotted line marks the position where the irradiated sample lengths are equal for both slit settings. The parameters used were L = 330 mm, ° and for the fixed-slit case and S = 12 mm in the case of variable slits. |
