Abstract: We present a final report on our program to raise the Technology Readiness Level (TRL) of enhanced charge-coupled-device (CCD) detectors capable of meeting the requirements of X-ray grating spectrometers (XGS) and wide-field X-ray imaging instruments for small, medium, and large missions. Because they are made of silicon, all X-ray CCDs require blocking filters to prevent corruption of the Xray signal by out-of-band, mainly optical and near-infrared (near-IR) radiation. Our primary objective …
