Description
The proposed Electron-Ion Collider will explore the physical regime of the most fundamental particles, quarks and gluons, and their interactions, which create 95% of the mass of the visible matter in the universe. To analyse these collisions a sophisticated particle id system must be built. The Detection of Internally Reflected Chereknov light (DIRC) technology is an attractive and radially compact solution for charged particle identification at an EIC in the barrel region not accessible by traditional RICH detectors. I will describe the status of the design and R&D for the High Resolution DIRC envisioned for an EIC detector. The current design of High Resolution DIRC at EIC will use a new, innovative compound lens to reach remarkable resolution sufficient to extend the momentum coverage well beyond state-of-the-art, up to 6 GeV/c. Performance of a prototype of the compound lens was tested on test benches and in particle beam at CERN, and results will be presented.
