Caption

The electromagnetic calorimeter (ECAL) consisted of 21×21×11 LYSO crystals, each measuring 2.5×2.5×4 cm3, covered by ESR, and read out using silicon photomultiplier (SiPMs). To enhance detection efficacy and prevent particles from traversing through gaps, crystals in successive layers were staggered by half the crystal's transverse dimension.
