“…An optical filter is typically required for detectors on X-ray telescopes because light from stars and other background sources will otherwise contaminate the X-ray images but the optical blocking filters are typically deposited on a substrate that is mounted separately from the X-ray detector. Transmission curves at wavelengths from 180-1000 Å for the different aluminum filters are reported in [6]. Each detector in this experiment is half covered by the aluminum filter, the other half has no filter.…”

Si Hybrid CMOS detectors (HCDs) are sensitive to X-rays between approximately 0.2 -20 keV. HCDs can provide superior performance to traditional CCDs in multiple areas: faster read out time, windowed read out mode, less susceptible to radiation & micrometeoroid damage, and lower power consumption. X-ray detectors designed for use in astronomical observatories must have an optical blocking filter to prevent the detectors from being saturated by optical light. We have previously reported on the successful deposition of an Al optical blocking layer directly onto the surface of HCDs. These blocking filters were deposited with multiple thicknesses from 180 -1000 Å and successfully block optical light at all thicknesses, with minimal impact expected on quantum efficiency at the energies of interest for these detectors. The thin Al layer is not expected to impact quantum efficiency at the energies of interest for these detectors. We report energy dependent soft X-ray quantum efficiency measurements for multiple HCDs with different optical blocking filter thicknesses.

“…Given the history of earlier TIS CMOS-Hybrid FPAs such as the H2RG [7], we were less concerned with the ability of the FPA to meet these performance parameter goals and were more concerned with hybridization yield and electronics cross-talk. It was our assessment that the ability to correctly deposit, align and connect nearly 17 million In bumps would prove to be extremely challenging, and could have a significant negative impact on overall FPA yield.…”

We present both laboratory and telescope testing results describing the performance of the H4RG-10 CMOS-Hybrid detector. The H4RG-10 is the largest visible hybrid array currently in existence and shows great potential for use in future space missions. We report read noise, dark current, pixel connectivity, persistence, and inter-pixel capacitance measurements for the temperature range 110-240 K. We report on quantitative astrometric and qualitative photometric performance of the instrument based on observations made at USNO's Flagstaff Station observatory and establish an upper limit to the astrometric performance of the detector. We discuss additional testing and future work associated with improving detector performance.

“…The X-ray astronomy community can benefit from past developments that have already led to the maturity of hybrid CMOS detectors (HCDs) for optical and infrared applications [2,3,4]. These prior developments have brought the technology readiness level of the devices and their readout ASICS to a high level, thus bringing us to the point where relatively small modifications are all that is required to enable their use in future X-ray missions.…”

Future space-based X-ray telescope missions are likely to have significantly increased demands on detector read out rates due to increased collection area, and there will be a desire to minimize radiation damage in the interests of maintaining spectral resolution. While CCDs have met the requirements of past missions, active pixel sensors are likely to be a standard choice for some future missions due to their inherent radiation hardness and fast, flexible read-out architecture. One form of active pixel sensor is the hybrid CMOS sensor. In a joint program of Penn State University and Teledyne Imaging Sensors, hybrid CMOS sensors have been developed for use as X-ray detectors. Results of this development effort and tests of fabricated detectors will be presented, along with potential applications for future missions.
