DuPont's Investment in the APS: "Better Rings for Better Things for Better Living". Richard L. Harlow (representing the Braggnet Group), Central Research and Development, E228/316d, The DuPont Company, Wilmington, DE, 19880-0228.

The DuPont Company has joined with the Dow Chemical Company and Northwestern University to build and operate one sector at the Advanced Photon Source under the CAT name of DND. Experiments in the areas of catalysis, polymer processing and structural analysis have been given the highest priority. Building on the successes and failures of our collective experiences at Brookhaven's NSLS, we have designed beamlines and experimental stations at the APS to specifically take advantage of the high brilliance and short wavelength radiation. The former will be used for example to study uniformity of single-filament fibers and to obtain diffraction data on very small protein crystals. The latter will be used to probe catalysts in pressure vessels under actual plant operating conditions and to collect (nearly) absorption-free diffraction data from single crystals of heavy-metal oxides. General goals are to collect a multiple types of data during any one experiment or to use multiple wavelengths: simultaneous WAXS and SAXS on polymer samples; simultaneous powder diffraction and EXAFS on catalysts; simultaneous two-wavelength EXAFS on metal-doped materials. Time-resolution is also critical: catalyst kinetics and "jump" experiments on polymers are but two examples.
