Beamline Snapshot

ID21


X-ray Microscopy Beamline

Scanning X-ray microscope (SXM) / Fourier-transform infrared microscope (FTIR)

ID21 comprises two endstations: (a) a scanning X-ray microscope (2-9 keV) optimized for X-ray micro-fluorescence and micro-spectroscopy imaging of elemental distributions and chemical speciation of samples (sub-micron lateral resolution), and (b) an endstation devoted to infrared spectro-microscopy in the mid-infrared range.
