Figure 2
Illustration of the geometry of the low-resolution diffraction camera. Dimensions are in mm. (For clarity, the scale is expanded in the vertical direction by a factor of about 70 relative to the horizontal.) The collimating slits S0 and S1 act as a source of unwanted scattered radiation which can appear as linear streaks extending into the diffraction pattern outwards from the beam centre. This scatter is confined to lie inside the area obscured by the beamstop (shaded area) by the use of a guard aperture, in this case a modified collimator nose piece. Low-resolution diffracted X-rays (shown in red labelled hkl) pass through the He path and are incident on the detector surface. |
