论文摘要
电子离子对撞机（EIC）将是美国核物理学的下一个前沿项目。它计划与杰斐逊实验室密切合作，在布鲁克黑文国家实验室（BNL）建造。 EIC中央检测器的关键要求之一是出色的粒子鉴定（PID）。使用内部反射的Cherenkov Light（DIRC）原理的检测器，其径向仅为7-8 cm，是一种非常有吸引力的解决方案，用于识别最终状态下的Hadron。 The R$\&$D program performed by the EIC PID collaboration (eRD14) is focused on designing a high-performance DIRC (hpDIRC) detector that would extend the momentum coverage well beyond the state-of-the-art 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 $。 HPDIRC检测器的关键组件是3层化合物透镜和小像素大小的照片传感器。本文介绍了EIC检测器的高性能DIRC R $ \＆$ D的状态，重点是为开发和验证辐射硬式3层镜头的努力。
The Electron-Ion Collider (EIC) will be the next frontier project of nuclear physics in the United States. It is planned to be built in the Brookhaven National Laboratory (BNL) in close collaboration with Jefferson Lab. One of the key requirement for the EIC central detector is excellent particle identification (PID). A detector using the Detection of Internally Reflected Cherenkov light (DIRC) principle, with a radial size of only 7-8~cm, is a very attractive solution for identification of the hadrons in the final state. The R$\&$D program performed by the EIC PID collaboration (eRD14) is focused on designing a high-performance DIRC (hpDIRC) detector that would extend the momentum coverage well beyond the state-of-the-art 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/$c$. Key components of the hpDIRC detector are a 3-layer compound lens and small pixel-size photo-sensors. This article describes the status of the high-performance DIRC R$\&$D for the EIC detector, with a focus on efforts towards developing and validating the radiation hard 3-layer lens.
