Status of x-ray hybrid CMOS development efforts at PSU

Future X-ray missions of all sizes will demand higher readout rates than current CCDs can handle due to the increased effective area of these missions and the resulting increased significance of pile-up issues. Silicon hybrid CMOS X-ray detectors, or HCDs, have significant advantages over CCDs for use on next-generation X-ray missions due to their fast and flexible readout abilities, inherent radiation hardness, and low power requirements. The Penn State High Energy Astrophysics Detector and Instrumentation Lab, in collaboration with Teledyne Imaging Sensors, is leading the effort to design and develop next-generation X-ray HCDs. We discuss the results of this development effort and present the current testing results of next-generation X-ray HCDs that are suitable for high-throughput and high-angular-resolution X-ray missions of the future.
