Performance Studies of SiPM-on-Tile Calorimetry for the ePIC Detector at NSRL and STAR
ORAL
Abstract
The SiPM-on-Tile technology has been adopted in several calorimeter subsystems of the ePIC detector at the future Electron-Ion Collider (EIC), including the forward and backward hadronic calorimeters (1.5 < η < 3.0), the high-granularity Calorimeter Insert (3.0 < η < 4.0), and the Zero-Degree Calorimeter (ZDC, η > 6.0). To validate the design and assess performance under realistic conditions, dedicated prototypes were developed and tested at Brookhaven National Laboratory (BNL).
At the NASA Space Radiation Laboratory (NSRL), we conducted a systematic study of SiPM radiation response, characterizing pedestal stability, and MIP calibration as a function of accumulated dose. Complementary tests were performed in the STAR experimental hall, where the prototypes were exposed to 200 GeV Au+Au collisions to evaluate their response, and stability in a realistic high-rate environment. Together, these studies provide a comprehensive validation of the SiPM-on-Tile technology and inform design optimizations for the ePIC forward calorimetry systems.
