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 ultrasmall-, small- & wide- angle X-ray scattering (combined USAXS/SAXS/WAXS) capabilities. The setup uses a monochromatic, highly collimated, and intense beam in the pinhole configuration with sample-to-detector distance variable from 0.8 m to 31 m. The collimation is achieved by exploiting the intrinsic low divergence of the source together with two slits placed farther apart. Using 1 Å X-ray wavelength, the q range covered by the instrument is roughly 10^-3 nm^-1< q < 60 nm^-1. 

More detailed information about the scattering techniques, sample environments, and detectors is available at the beamline home page, which also lists recent publications illustrating the capabilities of the instrument.  An up-to-date reference for the beamline technical specifications and performance is Ref. [1]. Please note that the beamline web page is not a reference and the link is subject to change. For experiments carried out prior to 2020, the technical reference is still Ref. [2].
