Abstract

The high-performance DIRC (hpDIRC) detector for the Electron–Ion Collider (EIC) has progressed from design optimization to extensive experimental validation in preparation for construction. The baseline design, developed and optimized using detailed Geant4 simulations, has reached a mature stage and is advancing toward production readiness. A modular prototype, designed to validate key optical and readout components at the Cosmic Ray Telescope (CRT) facility at Stony Brook University, is in the commissioning phase, with first measurements expected in mid-2026. In parallel, disassembly and refurbishment of legacy BaBar DIRC radiator bars that is ongoing at Jefferson Lab, combined with a comprehensive optical quality-assurance program, represents a major milestone toward the Technical Design Report (TDR).
