摘要:

将在布鲁克海文国家实验室(BNL)建造的高亮度、高能量电子-离子对撞机(EIC)将为研究高能与核物理领域的若干基础问题提供洁净的实验环境。为实现对初级顶点与次级顶点的精确测量,以及具备良好动量分辨率和空间分辨率的径迹重建,需要一款高粒度、低物质量的硅顶点与径迹探测器。EIC硅顶点与径迹探测器的参考设计包含基于单片有源像素传感器(MAPS)的顶点与径学子系统,以及基于交流耦合低增益雪崩二极管(AC-LGAD)的外层径迹探测器,可在赝快度区间-3.5至3.5内实现全方位角覆盖的径迹重建。新组建的ePIC合作组正在基于EIC项目探测器参考设计,结合新型磁体开展进一步的探测器几何结构优化工作。本次将介绍最新的ePIC顶点与径迹探测器几何结构,以及通过仿真评估得到的性能表现。同时还将讨论EIC硅顶点与径迹探测器研发的相关细节,包括拟采用的探测器技术、原型传感器的性能表征以及探测器的机械设计。

英文摘要:

The high-luminosity high-energy Electron-Ion Collider (EIC) to be built at Brookhaven National Laboratory (BNL) will provide a clean environment to study several fundamental questions in the high energy and nuclear physics fields. A high granularity and low material budget silicon vertex and tracking detector is required to provide precise measurements of primary and displaced vertex and track reconstruction with good momentum and spatial resolutions. The reference design of the EIC silicon vertex and tracking detector includes the Monolithic Active Pixel Sensor (MAPS) based vertex and tracking subsystem and the AC-Coupled Low Gain Avalanche Diode (AC-LGAD) based outer tracker, and it has the track reconstruction capability in the pseudorapidity region of -3.5 to 3.5 with full azimuthal coverage. Further detector geometry optimization with a new magnet based on the EIC project detector reference design are being performed by the newly formed ePIC collaboration. The latest ePIC vertex and tracking detector geometry and its performance evaluated in simulation will be presented. Details of the EIC silicon vertex and tracking detector R$\&$D, which include the proposed detector technologies, prototype sensor characterization and detector mechanical design will be discussed as well.
