论文摘要
像素亮度望远镜是一种用于LHC的CMS实验的亮度测量的硅像素检测器。它位于距交互点约1.75 m的位置，并安排到16个“望远镜”中，在探测器的任何一端，在梁管周围安装了八个望远镜，每个望远镜由三个单独的硅传感器平面组成。每束瞬时亮度是通过计算事件来衡量的，在望远镜登记处的所有三个飞机都使用特殊的读数，以40 MHz为40 MHz。完整的像素信息以较低的速度读取，可用于确定在线和离线测量值的校准，校正和系统的不确定性。本文详细介绍了LHC运行2（2015-18）期间检测器的调试，操作历史和性能，以及将于2022年开始的Run 3的准备工作。
The Pixel Luminosity Telescope is a silicon pixel detector dedicated to luminosity measurement at the CMS experiment at the LHC. It is located approximately 1.75 m from the interaction point and arranged into 16 "telescopes", with eight telescopes installed around the beam pipe at either end of the detector and each telescope composed of three individual silicon sensor planes. The per-bunch instantaneous luminosity is measured by counting events where all three planes in the telescope register a hit, using a special readout at the full LHC bunch-crossing rate of 40 MHz. The full pixel information is read out at a lower rate and can be used to determine calibrations, corrections, and systematic uncertainties for the online and offline measurements. This paper details the commissioning, operational history, and performance of the detector during Run 2 (2015-18) of the LHC, as well as preparations for Run 3, which will begin in 2022.
