DND-CAT:
The Synchrotron Research Center manages the operations of the DuPont-Northwestern-Dow Collaborative Access Team (DND-CAT) instrumentation at the Advanced Photon Source at Argonne National Laboratory. Funds for construction, management, and operations to date have been obtained from E.I. DuPont de Nemours & Co., the Dow Chemical Company, the National Science Foundation through the Academic Research Infrastructure program and the Materials Research Center , the State of Illinois through the Department of Commerce and Community Affairs and the Higher Education Cooperation Act, and the US Department of Energy. University sources of funds include the McCormick School of Engineering and Applied Science, the office of the Vice President, and the Office of Research. The facility supports state of the art x-ray research in the fields of biology, physics, chemistry, chemical engineering, environmental science, and materials science and engineering.

DND-CAT EQUIPMENT:

DND-CAT operates five experimental stations. Three of these utilize undulator radiation and two utilize a part of the dipole radiation fan. DND-CAT currently supports several interdisciplinary X-ray techniques including x-ray spectroscopy, macromolecular and inorganic crystallography, small angle x-ray scattering, x-ray tomography and powder diffraction.

LS-CAT:

The Life Sciences Collaborative Access Team (LS-CAT) provides macromolecular cystallography resources for those with a need to determine the structure of proteins. Mainly LS-CAT provides access to state of the art x-ray diffraction facilities at Argonne National Laboratory's Advanced Photon Source where extremely intense beams of x-rays are focused using both mirrors and beryllium lenses onto tiny protein crystals. The x-rays diffracted by these crystals are collected with giant CCD detectors that produce the images needed to calculate where the atoms in the protein crystal are.

LS-CAT was formalized in 2003 with seed money from the State of Michigan through the Michigan Core Technology Alliance. Northwestern University was selected as the managing partner and personnel from the du Pont-Northwestern-Dow Collaborative Access Team (DND-CAT) started work on the design of the facilities.

Construction of the LS-CAT facilities started in January 2006. By December, 2006 the construction of the x-ray enclosures had been completed and the instrumentation of the main station, 21-ID-D, was far enough along to accommodate an aggressive experimental schedule.

Sadly, one of the driving forces behind the formation of LS-CAT, Martha Ludwig, passed away in late November, 2006, just days before the first x-rays were delivered at LS-CAT for its members. The experimental facilities at 21-ID are dedicated in her honor.

Current LS-CAT members are Michigan State University, University of Michigan, Wayne State University, Van Andel Research Institute, Northwestern University, University Wisconsin-Madison, Vanderbilt University, and University of Illinois at Urbana-Champaign.

LS-CAT EQUIPMENT:

The LS-CAT facilities include four experimental stations using 2 insertion devices. The main beamline (21-ID-D) uses a shortend "Undulator" A and a Kohzu monochromator in a layout very similar to XOR Sector 4 and Northeastern Collaborative Access Team (NE-CAT), APS Sector 24.
In addition to the main beamline there are three experimental stations that share a single 3.0 CM undulator. The first two of these stations use diamond laue monochromators supplied by JJ X-Ray along with beryllium lenses to focus a beam monochromatic x-rays onto the sample. This allows SAD experiments to be done at the selenium edge (12.668 KeV). This arrangement is very similar to the ID14 beamline at the ESRF.
