Presentation #103.53 in the session Missions and Instruments.
The AstroPix detector enables novel designs of Compton and Pair telescopes by enhancing the tracking of secondary charged particles produced through interactions with incident astrophysical gamma-rays. AstroPix is a monolithic Complementary Metal-Oxide-Semiconductor (CMOS) active pixel sensor that combines low noise operation with precise interaction location knowledge by embedding charge collection, signal amplification, and signal discrimination within each pixel. A sounding rocket flight of a prototype multi-layered AstroPix instrument will demonstrate the maturity of the technology and its capacity to improve the next generation of gamma-ray observatories for advancing the exploration of time domain astronomy and multi-messenger astrophysics. Updates to the frontend readout and backend data handling hardware and firmware inherited from testing AstroPix’s precursor, ATLASPix, will yield a compact, low-power, flight-ready instrument payload. We present the current design and state of development of an AstroPix multi-layer payload for a planned sounding rocket technology demonstration.
