Figure 7
The mass attenuation coefficient of zinc from foils of different thickness: (a) without dark current offset (i.e. assuming the determinations of dark current are correct to within 0.5 counts); with dark current offset of (b) 1 counts s−1, (c) 4 counts s−1 and (d) 6 counts s−1. The oscillatory pattern above the edge was not observable for the thickest foil, confirming that the measured dark currents were accurate to within 0.5 counts.
