为未来电子离子对撞机研制高性能DIRC探测器

Developing high-performance DIRC detector for the Future Electron Ion Collider Experiment

Greg Kalicy

摘要:

电子-离子对撞机(EIC)将是美国核物理的下一个前沿项目。它计划与杰斐逊实验室密切合作,在布鲁克海文国家实验室(BNL)建造。EIC中心检测器的关键要求之一是出色的粒子识别(PID)。利用内反射切伦科夫光(DIRC)原理,径向尺寸仅为7-8厘米的探测器,是一种很有吸引力的末态强子鉴别方案。由EIC PID合作组织(eRD 14)执行的R $\&$ D计划专注于设计高性能DIRC(hpDIRC)探测器,该探测器将扩展动量覆盖范围,使其远远超过$π/K$高达6~GeV/ $c$、$e/π$高达1.8~GeV/ $c$和$p/K$高达10~GeV/ $c$的最新3个标准差或更多分离。hpDIRC探测器的关键部件是一个3层复合透镜和小像素尺寸的光电传感器。本文介绍了用于EIC探测器的高性能DIRC R $\&$ D的现状,重点介绍了抗辐射3层透镜的开发和验证工作。

英文摘要:

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.
