Description

AstroPix is a high-voltage CMOS monolithic active pixel sensor (HVCMOS MAPS) originally developed for space-based missions, specifically for gamma-ray astrophysics. Its precise energy and position resolution, low noise, and low power consumption, combined with minimal dead material, meet the performance requirements for the Barrel Imaging Calorimeter (BIC) in the ePIC detector for the future Electron-Ion Collider. As a key component of the BIC, the 4 (+2) AstroPix imaging layers, interleaved with Pb/SciFi calorimeter layers, play a crucial role in position resolution, electron/pion separation, and shower profiling. This talk will provide an overview of AstroPix R&D, along with performance results from both bench and beam tests.
