Beamlines and Facilities: Beamline:2-ID-D
The 2-ID-D/E beamline encompasses three hard x-ray microprobes for x-ray fluorescence mapping, fluorescence spectroscopy, and microdiffraction. Station 2-ID-E is an x-ray fluorescence microprobe in a side-branch geometry, which operates in parallel to 2-ID-D. Station 2-ID-D contains an x-ray fluorescence and a micro-diffraction microprobe, which operate exclusively.
Beamline 2-ID-D is devoted to sub-micron high resolution x-ray imaging studies. Most work on the beamline centers on fluorescence analysis of biological samples and micro diffraction of a variety of materials.
