This paper describes the mechanical design, the readout chain, the production, testing and the installation of the Silicon Microstrip Tracker of the D0 experiment at the Fermilab Tevatron collider. In addition, description of the performance of the detector during the experiment data collection between 2001 and 2010 is provided.

A lot of R & D work is carried out in the CERN RD50 Collaboration to find out the best material for the Si detectors that can be used in the harsh radiation environment of HL-LHC, n and p-MCz Si was identified as one of the prime candidates as a material for strip detector that can be chosen the phase 2 upgrade plan of the new Compact Muon Solenoid tracker detector in 2026. For the very first time, in this work, an advanced four level deep-trap mixed irradiation model for p-MCz Si is proposed by the comparison of experimental data on the full depletion voltage and leakage current to the Shockl…
FASER (ForwArd Search ExpeRiment) fills the axial blindspot of other, radially arranged LHC experiments. It is installed 480 meters from the ATLAS interaction point, along the collision axis. FASER will search for new, long-lived particles that may be hidden in the collimated reaction products exiting ATLAS. The tracking detector is an essential component for observing LLP signals. FASER's tracking stations use silicon microstrip detectors to measure the path of charged particles.This is a summary of one of FASER's latest papers "The tracking detector of the FASER experiment", which describes …
Silicon photomultiplier arrays - a novel photon detector for a high resolution tracker produced at FBK-irst, Italy
在FBK-irst研制了一个硅光电倍增器(SiPM)阵列,它有32个通道,尺寸为8.0 x 1.1 mm^2。每个250 um宽的通道被细分为5 x 22个矩形排列的像素。这些传感器被开发用于读出模块化高分辨率的光纤跟踪器。关键属性,如击穿电压,增益和光子探测效率(PDE)被发现是均匀的SiPM阵列的所有32个通道。如果噪声特性和PDE得到改善,这可以使具有SiPM阵列读出的光纤跟踪器成为可用跟踪器技术的有希望的替代方案。
Experimental Study of Different Silicon Sensor Options for the Upgrade of the CMS Outer Tracker
在计划于2027年左右开始的大型强子对撞机(HL-LHC)的高光度阶段,加速器预计将提供高达$7.5\times10^{34}$ cm $^{-2}$ s $^{-1}$的瞬时峰值光度。预计在未来十年内,$3000$或甚至$4000$ ~fb $^{-1}$的总积分亮度将被交付给通用探测器ATLAS和CMS,从而显著增加LHC实验的发现潜力。CMS探测器将为HL-LHC进行重大升级,全新的跟踪探测器由外部跟踪器和内部跟踪器组成。然而,新的跟踪系统将暴露在比当前跟踪器高得多的辐射下,需要新的抗辐射传感器。CMS从2009年开始发起了一项广泛的辐照和测量活动,系统地比较不同硅材料的特性和外跟踪器传感器的设计选择。在18种不同的晶圆材料、厚度和生产技术组合上设计并实现了几种测试结构和传感器。在用中子和不同能量的质子辐照之前和之后,对装置进行电气表征,其中通量对应于在$3000$ ~fb $^{-1}$之后CMS外跟踪器的不同半径处预期的通量。所执行的测试包括使用$β$源、激光和光束扫描的研究。本文比较了HL-LHC硅传感器的不同选择的性能,重点是硅块材料和厚度。

The strategies for and the performance of the CMS silicon tracking system alignment during the 2015-2018 data-taking period of the LHC are described. The alignment procedures during and after data taking are explained. Alignment scenarios are also derived for use in the simulation of the detector response. Systematic effects, related to intrinsic symmetries of the alignment task or to external constraints, are discussed and illustrated for different scenarios.
Performance studies of a pixel tracker in the Silicon Detector (SiD) concept for a future linear collider
使用SiD探测器的模拟框架来研究Higgs -> mumu衰变通道,表明可以通过提高带电粒子动量分辨率来实现信号显著性的显著增益。然而,对Z-> mumu衰减通道的更详细的模拟表明,通过增加跟踪器粒度无法实现分辨率的显着提高。相反,使用寿命较长的粒子对缺失/死顶点层进行的探测器稳定性研究显示了轨道分辨率的增加。现有的9.15 cm x 25 μm硅条几何形状被100 x 100微米硅像素取代,将次级顶点分辨率提高了100倍。通过使用密集射流对高度准直事件进行的研究表明,动量分辨率可以提高2倍,大大提高了信号的重要性,但需要将像素大小减小到25微米。将跟踪器粒度从9.15 cm条带升级到微米尺寸的像素需要增加传感器通道的数量和复杂性,但在大多数线性对撞机物理学中仅提供小的改进。
