Description
The Electron-Ion Collider (EIC) is a next-generation facility designed to address fundamental open questions in nuclear physics, including the origin of nucleon mass, the spin structure of the nucleon, and the emergent properties of dense gluonic matter.
The Barrel Imaging Calorimeter (BIC) is the electromagnetic calorimeter of the ePIC detector, designed to meet the stringent performance requirements of the EIC by providing precise energy measurements and particle identification for scattered electrons, photons, and neutral mesons.
The BIC is a high-granularity sampling calorimeter consisting of lead absorbers interleaved with scintillating fibers, complemented by pixelated imaging layers based on the AstroPix monolithic active pixel sensor. This hybrid design enables precise energy and position measurements, as well as three-dimensional shower reconstruction, making it a key detector for realizing the full physics potential of the EIC.
The BIC successfully completed its Preliminary Design Review in 2025 and is currently progressing toward the Final Design Review. This presentation will provide an overview of the BIC design and highlight recent developments of the AstroPix imaging layers, including detector characterization, beam-test performance, and ongoing system integration studies.
