Exploring the Rate Dependence of the CAEN DT5202 from the 2024 ePIC Forward Hadronic Calorimeter Test Beam

The Electron-Ion Collider (EIC) is a next-generation particle collider currently under joint development by Brookhaven National Lab and Thomas Jefferson National Accelerator Lab. Scheduled to begin taking data in the 2030s, the EIC will succeed the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. It will enable precision studies of electron-proton and electron-nucleus collisions. One of the planned detectors for the ePIC experiment at the EIC, the Longitudinally Segmented Forward Hadronic Calorimeter (LFHCal), is currently under development at Oak Ridge National Laboratory. As part of the preparation for the full detector, a prototype LFHCal module underwent a test beam in August 2024. Using data acquired with the CAEN DT5202, I investigated the rate dependence of the low-gain/high-gain correlation for different particle types: hadrons, muons, electrons, and pions. By applying cuts based on event timestamps, we isolate high- and low-rate conditions to study the response of the CAEN unit and its saturation behavior at varying event rates. This poster will present key insights into rate-dependent behavior that will inform both the interpretation of past test beam data and the optimization of future detector performance.
