良好的粒子识别（PID）是未来电子-离子对撞机（EIC）探测器的基本要求。末态强子的识别对于研究不同夸克味对核子性质的影响至关重要。基于内反射切伦科夫光（DIRC）原理的探测器，其径向尺寸仅为几厘米，是满足这些要求的完美解决方案。EIC PID联盟（eRD 14）进行的研发过程专注于设计一种高性能的DIRC，该DIRC将扩展动量覆盖范围，远远超出最先进的水平，允许3个标准差或更多的分离π/K高达6 GeV/c，e/π高达1.8 GeV/c，p/K高达10 GeV/c。达到这种性能的关键部件是特殊的3层复合透镜。本文介绍了用于EIC探测器的高性能DIRC的研发现状，重点介绍了三层透镜的详细蒙特卡罗模拟结果和性能测试。
Excellent particle identification (PID) is an essential requirement for a future Electron-Ion Collider (EIC) detector. Identification of the hadrons in the final state is critical to study how different quark flavors contribute to nucleon properties. A detector based on the Detection of Internally Reflected Cherenkov light (DIRC) principle, with a radial size of only a few cm, is a perfect solution for those requirements. The R&D process performed by the EIC PID consortium (eRD14) is focused on designing a high-performance DIRC that would extend the momentum coverage well beyond the state-of-the-art, allowing 3 standard deviations or more separation of π/K up to 6 GeV/c, e/π up to 1.8 GeV/c, and p/K up to 10 GeV/c. A key component to reach such a performance is a special 3-layer compound lens. This article describes the status of the High-Performance DIRC R&D for the EIC detector, with a focus on the detailed Monte Carlo simulation results and performance tests of the 3-layer lens.
