Description
The ePIC experiment at the Electron-Ion Collider (EIC) seeks to uncover the fundamental structure of nucleons and nuclei. The Barrel Imaging Calorimeter (BIC) is an important detector designed to provide high energy and position resolution for photons and electrons. As part of its development, a prototype BIC was built and subjected to a beam test at the CERN PS beamline. In the beam test, calibration and energy measurement under realistic conditions were conducted. Each 3×3×32 cm^3 Pb/SciFi module was assembled by layering swaged lead plates with scintillating fibers, which were then bundled and read out by photomultiplier tubes to detect signals from electromagnetic showers. A prototype assembly, arranged in a 3x5 matrix of these unit modules, was deployed to evaluate energy response. In this talk, we present the design, assembly, and beam-test preparations for the prototype BIC. These efforts will validate the Pb/SciFi bulk domain performance and help refine the manufacturing process in anticipation of full-scale production.
