Pushing the envelop of sulfur SAS structure determination at UGA/SER-CAT

1 small variability to cover Se and Br edges). The 24ID-E beamline is equipped with a MD2 microdiffractometer, which is used to provide stable and well collimated beam from 5 to 100 microns in diameter and capable of visualizing micron-sized crystals. These operational beamlines are currently open to general APS users. Installation of a bending magnet beamline is now in progress and expected to be completed by the end of this year. NE-CAT is a consortium of scientists organized to design, construct and operate a structural biology sector at the APS. This facility will be used to focus on NECAT research on structural studies involving technically challenging crystallographic projects. In order to meet these needs, an ALS robot for screening a large number of crystals is now being commissioned, a microfocus diffractometer MD-2 is installed on 24ID-E beamline and several novel hardware and software ideas will be implemented. Funding for NE-CAT is provided through P41 grant from the National Center for Research Resources and from the NE-CAT member institutions.
