This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Speedster-EXD550 hybrid CMOS detectors (HCDs) implement event-driven readout, enabling only those pixels with X-rays to be readout and dramatically increasing the effective readout speeds. In this work, we optimize and characterize detector performance of the Speedster-EXD550, particularly the energy resolution in preparation for use in future missions, including the upcoming BlackCAT CubeSat. BlackCAT is a NASA CubeSat mission using an array of four Speedster- EXD550 hybrid CMOS detectors (HCDs). The purpose of this mission is to search for high- redshift gamma-ray bursts and other high-energy transients.

Available in PDF, EPUB and Kindle. Book excerpt: For space-based X-ray applications, silicon hybrid CMOS detectors (HCDs) offer many advantages over CCDs, such as faster readout rates and in-pixel circuitry. Achieving low noise in X-ray applications of HCDs helps to achieve better energy resolution, so understanding their dark current and read noise is a high priority. Dark current is temperature dependent, so cooling the detector is the best way to minimize its effects. Cooling detectors is costly for CubeSats, so it is important to characterize dark current at the temperatures the detectors will see in orbit. The BlackCAT Cube- Sat is a Coded Aperture Telescope that will search the soft X-ray sky for high-energy astronomical transients. It is a 6U CubeSat mission using an array of four Speedster-EXD550 X-ray HCDs. Here, we analyze the dark current of 2 Speedster-EXD550s.
