Figure 5
Attenuations of seven silver foils with nominal thicknesses ranging from 5 µm to 275 µm, using equation (4), versus nominal monochromator energy. At least three measurements using different thicknesses of foils were made at each energy. Measurements using all the foils were made at 17 keV where the area raster scan of the reference foil (100 µm thick) was made. The attenuation of the various sample thicknesses are represented by the different symbols as indicated. |
