Beamline 11-ID-D: Sector 11 - Time Resolved X-ray Spectroscopy and Scattering

X-ray Science Division, APS
Chemistry, Environmental Science, Materials Science

Description

The beamline provides time-resolved (TR) X-ray absorption spectroscopy (XAS) and scattering (XS) tools to visualize ultrafast structural dynamics during processes related to energy conversion or storage. Two inline undulators together with optimized beamline optics and a high heat load double-crystal monochromator provide 11-ID-D with high flux X-ray (10E13/photons/sec) tunable from 6 keV to 25 keV. A laser hutch next to D station hosts two laser systems, providing intense laser pulses as the excitation source.
