Description
AstroPix is an HV-CMOS monolithic silicon sensor and one of the main components along with the Pb/SciFi calorimeter of the Barrel Imaging Calorimeter (BIC) for the ePIC. Interleaved with the calorimeter layers, the AstroPix layers enable meeting the performance requirements for the Barrel Imaging Calorimeter, including electron/pion separation and gamma/pion discrimination.
The sensor has been developed, based on the ATLASPix sensor design, for NASA's All-sky Medium-Energy Gamma-ray Observatory eXplorer (AMEGO-X) mission and tested in parallel at Argonne National Laboratory (ANL) in a bench environment. In addition, the Astropix version 3 has been recently tested at the Fermilab Test Beam Facility (FTBF) in an integrated prototype with the SciFi/Pb calorimeter as a part of the project R&D.
This talk will present the preliminary results from the AstroPix sensor (version 3) performance test at ANL and the beam test at FTBF.
