Figure 5
(a) Correlation between I₀ and I₁. The left y-axis shows the intensity of I₀ (blue) and I₁(green) over time; the right y-axis (red) shows the ratio of I₁ and I₀. (b Importance of I₀ in the extraction of the absorption spectrum of Fe foil. The left y-axis shows the intensity of I₀ (solid line) and that of I₁ (dashed line); the right y-axis shows the absorbance of Fe foil which is calculated by abs = ln(I₀/I₁). We note that each Fe foil absorption spectrum is contributed to by 50 X-ray pulses.
