ID02 - Time-Resolved Ultra Small-Angle X-Ray Scattering

Synopsis

ID02 beamline is a combined ultra small-angle and wide-angle scattering instrument. The microstructure and non-equilibrium dynamics of soft matter and related systems can be probed from sub-nanometer to micron scale, and down to sub-millisecond time range.

Technical details

COMBINED USAXS/SAXS/WAXS: ID02 offers time-resolved ultra small- & wide- angle X-ray scattering (combined USAXS/SAXS/WAXS). The setup uses the monochromatic, highly collimated, and intense beam in a pinhole configuration with sample-to-detector distance variable from 0.6 m to 30 m. USAXS configuration employs a double crystal collimation scheme to reduce the horizontal beam divergence. Using 1 Å X-ray wavelength, the q range covered by the instrument is roughly 10^-3 nm^-1< q < 60 nm^-1. MORE INFORMATION: Detailed information on available techniques, sample environments, and detectors is available at the beamline home page, which also lists recent publications demonstrating the beamline's capababilities.
