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 usually achieved using slits but the high resolution USAXS configuration may also employ 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
