Summary

• The DuPont-Northwestern-Dow Collaborative Access Team (DND-CAT) at the Advanced Photon Source (APS) supports a variety of X-ray scattering techniques ideally suited to the study of polymers. The 5ID-D experimental enclosure, in particular, is focused on small and wide angle scattering (SAXS and WAXS).

• Five sets of slits, camera lengths up to 10 m, and a remote sample changer mounted in vacuum provide ultra-low-background pinhole-camera SAXS data down to 0.001 Å-1. Dynamic studies of crystallization, melting, and deformation are possible using the available Linkam thermal stage, Differential Scanning Calorimetry (DSC) cell, or Instron servo-hydraulic system. Most SAXS data are best collected on the low-noise, Mar USA Inc, 162 mm, marCCD camera; however, scattering data from a transitioning sample can be collected at rates up to 3.8 Hz on the Roper Scientific® simultaneous SAXS/WAXS area detector system.

• These features of 5ID-D, in addition to the other techniques available, make DND-CAT an excellent resource for polymer studies.
