Developments in X-ray detectors at the Advanced Photon Source

We present a progress report on some of the X-ray detector developments on-going at the Argonne National Laboratories Advanced Photon Source. We focus on pixel array detector architecture, and emphasize collaborations, particularly with industries and universities. We discuss our progress establishing a silicon-sensor fabrication facility at Northern Illinois University, our application specific integrated circuit design work, X-ray testing and detector calibration, and readout electronics based on a collection of interchangeable digital circuit boards.
