Description
A next-generation gamma-ray observatory operating in the medium-energy gamma-ray band (~100 keV to 100 MeV) will provide crucial capabilities needed to identify and classify multi-messenger sources and to probe the explosive and energetic processes in the universe including relativistic jets and gamma-ray bursts. Advancements in tracker detector technologies and instrument design are critical for the operation of gamma-ray observatories searching for transients in the medium-energy gamma-ray regime. AstroPix is a high-voltage CMOS monolithic active pixel sensor under development for next-generation Compton and pair-production imaging telescopes. AstroPix detectors possess a large dynamic energy range (25-700 keV) with high spatial (500 x 500 um${^2}$) segmentation and spectral (<10% FWHM at 60 keV) resolution. The 2x2 cm$^{2}$ AstroPix detector digitizes photon and charged particle interactions on-chip and is optimized for low power consumption, targeting <1.5 mW/cm$^{2}$. Command and data handling is managed through chip-to-chip communication and simplifies large-scale detector plane integration. Improvements to the AstroPix design continue, primarily seeking to achieve full pixel depletion (500 um thick) and to further reduce power consumption. In this talk, I will discuss the continued progress in AstroPix detector development and highlight recent testing and calibration efforts.
