ID21 - X-ray Microscopy Beamline
Synopsis
The ID21 beamline is dedicated to micro and nano-X ray spectroscopy, 2D X-ray fluorescence (XRF) mapping and X-ray absorption spectroscopy (XAS), in the tender X-ray domain (2.1-10.5keV). These two techniques can be combined to acquire multi-energy XRF maps. Therefore, this beamline offers 2D elemental mapping and speciation information (in 0D, 1D and 2D), and is particularly optimized for the detection and chemical analysis of elements from P to Zn. Heavier elements can be analyzed through their L and M absorption edges. The beamline has recently been refurbished, and offers now two scanning X-ray microscopes: a new nanoscope (nano-SXM), optimized for high speed, high resolution (<180nm) nano-XRF mapping, and for nano-XAS, which complements and outperforms the "old" microscope, which has been preserved for the study of larger samples, with micrometric and submillimetric beam. Both microscopes are operated under vacuum, either at room temperature or in cryogenics conditions.
