摘要:

未来的电子-离子对撞机(EIC)将利用一系列高亮度高能电子+质子($e+p$)和电子+原子核($e+A$)碰撞来探索核子和原子核的内部结构以及物质的形成过程。EIC重味强子和喷注测量将在确定运动学约束不好区域的核子/核部分子分布函数和重夸克强子化过程中发挥重要作用。一个高粒度和低材料预算的前向硅跟踪器将使精确的前向重口味测量在EIC,这具有增强的灵敏度,以访问这些运动学的极端。正向硅跟踪器(FST)探测器正在设计中,并为EIC提供R $\&$ D。两种先进的硅技术,耗尽型单片有源像素传感器(DMAPS)和交流耦合低增益雪崩二极管(AC-LGAD),可以提供良好的空间和时间分辨率,已被认为是EIC硅跟踪探测器的候选人。介绍了FST概念设计和正在进行的DMAPS和LGAD探测器R $\&$ D的进展和结果。还将讨论集成EIC检测器的途径。

英文摘要:

The future Electron-Ion Collider (EIC) will utilize a series of high-luminosity high-energy electron+proton ($e+p$) and electron+nucleus ($e+A$) collisions to explore the inner structure of nucleon and nucleus and the matter formation process. Heavy flavor hadron and jet measurements at the EIC will play an essential role in determining the nucleon/nucleus parton distribution function and heavy quark hadronization process in not well constrained kinematic regions. A high granularity and low material budget forward silicon tracker will enable precise forward heavy flavor measurements at the EIC, which have enhanced sensitivities to access these kinematic extremes. A Forward Silicon Tracker (FST) detector is under design and R$\&$D for the EIC. Two advanced silicon technologies, the Depleted Monolithic Active Pixel Sensor (DMAPS) and the AC coupled Low Gain Avalanche Diode (AC-LGAD), which can provide fine spatial and timing resolutions, have been considered as candidates for the EIC silicon tracking detector. Progresses and results about the FST conceptual design and ongoing DMAPS and LGAD detector R$\&$D will be presented. The path towards an integrated EIC detector will be discussed as well.
