Figure 4
The background scattering from the adhesive compared with parafin. Graph showing the radial profile of the scattering density (averaged radial counts per pixel per micrometre of material in the X-ray beampath) of different mounts. The insets show the object producing the scattering: a large `Type A' adhesive droplet (a, solid black line), a small `Type B' adhesive droplet (b, dashed black line), `Type A' adhesive inside a CT-300 glass capillary (c, solid grey line) and a nylon loop with paraffin (d, dashed grey line). The scale bars represent 200 µm and the beam was collimated to 50 × 25 µm. |
