论文摘要

液体氩气中电子和光子传播的微物理学是检测器设计的关键组成部分,并且在广泛的粒子物理实验中构建和执行测量所需的校准。随着实验在规模和复杂性上的增长,并且随着预期测量的精度增加,必须开发研究影响该检测器的重要微物理效应的工具。在本文中,我们提出了液体氩中电子传输的新时间域蒙特卡洛模拟。模拟对近热电子的液体氩运输(翻译)进行了建模,目的是为研究和优化检测器环境提供多功能软件包,并特别关注正在进行的和下一代的液体氩气中微子实验,利用时间投影室内预测室技术。翻译基于Wojcik和Tachiya的先前工作,以及其他构建,引入了直至电离的其他横截面过程,从而对整个漂移电子散射相互作用进行了建模。该模拟通过基准通过在气体和液体中运行的实验设置中收集的数据进行基准的性能来验证其性能。

The microphysics of electron and photon propagation in liquid argon is a key component of detector design and calibrations needed to construct and perform measurements within a wide range of particle physics experiments. As experiments grow in scale and complexity, and as the precision of their intended measurements increases, the development of tools to investigate important microphysics effects impacting such detectors becomes necessary. In this paper we present a new time-domain Monte Carlo simulation of electron transport in liquid argon. The simulation models the TRANSport in Liquid Argon of near-Thermal Electrons (TRANSLATE) with the aim of providing a multi-purpose software package for the study and optimization of detector environments, with a particular focus on ongoing and next generation liquid argon neutrino experiments utilizing the time projection chamber technology. TRANSLATE builds on previous work of Wojcik and Tachiya, amongst others, introducing additional cross-section processes up to ionization, thus modeling the full range of drift electron scattering interactions. The simulation is validated by benchmarking its performance with swarm parameters from data collected in experimental setups operating in gas and liquid.
