Christian Lippmann

AI总结:

本文系统回顾了大型LHC实验中的粒子鉴别策略与技术,重点分析电离测量、飞行时间和切伦科夫成像三类方法,并以AMS 02为例展示天基实验中的综合应用。

摘要:

粒子鉴别(PID)是粒子物理实验的基础。本文回顾了大型LHC实验所使用的PID策略与方法,这些实验代表了当前最先进水平的杰出范例。第一部分重点介绍这些实验在PID方面的总体设计以及所采用的技术。文中详细讨论了三种PID技术:电离测量、飞行时间测量和切伦科夫成像。给出了这四种技术在LHC上实现的四个实例,并附有来自其他实验的相关实例选集以及新进展的简要概述。最后,简要描述了阿尔法磁谱仪(AMS 02)实验,将其作为一个令人印象深刻的天基实验范例,该实验使用了多种人们熟知的PID技术。

英文摘要:

Particle IDentification (PID) is fundamental to particle physics experiments. This paper reviews PID strategies and methods used by the large LHC experiments, which provide outstanding examples of the state-of-the-art. The first part focuses on the general design of these experiments with respect to PID and the technologies used. Three PID techniques are discussed in more detail: ionization measurements, time-of-flight measurements and Cherenkov imaging. Four examples of the implementation of these techniques at the LHC are given, together with selections of relevant examples from other experiments and short overviews on new developments. Finally, the Alpha Magnetic Spectrometer (AMS 02) experiment is briefly described as an impressive example of a space-based experiment using a number of familiar PID techniques.
