Figure 2
Sketch of the ReflEXAFS vacuum chamber installed at the GILDA beamline. The beam enters from the left and passes through the incident beam detector before hitting the sample. The sample is placed on a holder that provides movements for the horizontal and vertical alignment. Successive 90° rotations about the φ and χ axes permit the sample to be placed in front of the evaporator when required. The reflected beam is read by a photodiode placed after the chamber in the beam path whereas the fluorescence from the sample is read from the top by a 13-element high-purity Ge detector. A further opening for the side placement of the detector is also present but not shown in the drawing for clarity.
