Description
The Barrel Imaging Calorimeter (BIC), a subsystem of the Electron Ion Collider's ePIC detector, is a sampling calorimeter utilizing two technologies: scintillating fibers embedded in lead (Pb/ScFi), interleaved with AstroPix silicon sensors, providing the required energy and position resolutions and particle identification capabilities. A small Pb/ScFi calorimeter prototype, based upon a version of the GlueX Barrel Calorimeter with incorporated AstroPix sensors, has been tested in Summer 2024 at the Fermilab Test Beam Facility (FTBF) to benchmark the response to electrons and pions. Detailed simulations of the FTBF set up, necessary for performance benchmarking and BIC optimization studies, have been performed. The results from the beam test, together with the simulations, will be presented.
