ARGONNE MODULAR CCD DETECTOR. N.E.C. Duke, I. Naday, E.M. Westbrook, Center for Mechanistic Biology and Biotechnology, Argonne National Laboratory, Argonne, IL 60439, USA

A charge-coupled device (CCD) area detector, designed and built at Argonne National Laboratory and intended for use at the Advanced Photon Source (APS), is now in the process of being characterized and tested to demonstrate the detector's performance. Data will be presented regarding progress in this characterization program. The characteristics of this detector should make it nearly ideal for protein crystallography at beamlines 19-ID and 19-BM of the APS.
