Figure 2
Schematic showing how fluorescence yield from the sample is collected and analyzed at I20-scanning. In the upper left, I0, If and It are, respectively, the incident, fluorescent and transmitted intensities at the sample. In the lower left is a drawing of the 64 pixel germanium solid-state detector. Each pixel has an area of 5 × 5 mm. In the lower right, the fluorescence photons in the detector are shown separated from non-fluorescent scattering according to energy by a multi-channel analyzer. |
