11. Energy Measurements with monochromator (XAFS1) X-Ray incident beam goes to Crystal Monochromator and is then delivered to the experimental area. Energy can be selected with 0.1keV accuracy along the 5-15 keV range. 2 sensors (C04-W0110,D09-W0126) were tested in this beamline to obtain single pixel calibration for a subset of pixel (beam 2.5x3mm2) Analysis on one of the sample will be presented by Mateus Vincente for UFRJ
