AI 中文摘要
我们提供了对撞机上带电粒子计时的选择性概述。大致来说，三个时代捕捉了计时阵列的演变。虽然亮度和多重性决定了探测器技术，但也有必要回顾信号捕获和处理的多种方法，以及它们在变化的校准条件中的作用。对于当前时代——高亮度LHC升级——双阈值计时技术可以显著简化对幅度效应的关键修正。这种修正通常跨越的时间范围比目标分辨率大一个数量级。此外，由于在高辐射环境下运行条件会变化，校准不能再被视为一次性程序。为CMS升级设计的TOFHIR2C ASIC可以配置为提供双阈值计时。在本报告中，我们利用这一能力来展示这种适用于我们新时代的技术的威力。
英文摘要
We give a select overview of charged particle timing at colliders. Roughly speaking, three eras capture the evolution of timing arrays. While luminosity and multiplicity dictate the detector technologies, there is also a need to review the various approaches to signal capture and processing, and their role in changing conditions for calibration. For the current era--the High-Luminosity LHC upgrades--the technique of dual-threshold timing can significantly simplify the crucial correction for amplitude walk.This correction often spans a time range an order of magnitude larger than the target resolution. Furthermore, because operating conditions vary in the high radiation environment, calibration can no longer be thought of as a one-time procedure. The TOFHIR2C ASIC designed for a CMS upgrade can be configured to provide dual threshold timing. In this report, we use this capability to demonstrate the power of this technique suitable for our new era.}
