The Backward Hadronic Calorimeter (nHCal) of the ePIC Experiment at EIC
Year: 2026
Type: conference-paper
Abstract: The planned Electron-Ion Collider (EIC) at Brookhaven National Laboratory will be a unique, high-luminosity accelerator which will explore the parton and spin structure of protons and nuclei by colliding polarized electrons with polarized protons and ions. The ePIC (electron-Proton/Ion Collider) detector will be the first general-purpose detector designed for the EIC, covering a wide area in the $x_{Bj} - Q^{2}$ across a range of center-of-mass energies. The backward hadronic calorimeter (nHCal) will be crucial for low-$x_{Bj}$ measurements, which are essential to the EIC's physics program. This detector will enhance hermeticity and improve scattered electron tagging by serving as a hadronic veto. This proceeding presents the design, physics motivation, and expected performance of the nHCal.
