Chemistry, Environmental Science, Materials Science
General purpose x-ray spectroscopy beamline with multiple detection and sample environment capabilities. A toroidal focusing mirror is standard to 32 keV. Unfocused the energy range increases to 35 keV. Variable-angle harmonic-rejection mirror can also focus vertically to 30 micron. A polycapillary optic can provide a high flux 25 micron focus. We are currently operating in full general user mode. In-situ measurements require close coordination with beamline staff and on-site experimental support from user group.
