Figure 2
Experimental schematic to potentially simultaneously measure photo-absorption (transmittance) and X-ray fluorescence. Vertically polarized X-rays are incident on the sample rotated to 45°. The forward placed photodiode allows for a measure of A(E), when compared with the incident flux, and the CCD can detect the isotropic XRF emission. The CCD detector is rotated by 90° to limit scattering signal that may otherwise contaminate the XRF signal. |
