论文摘要
FASER是一个正向搜索实验,是一个实验,致力于在CERN的大型强子对撞机(LHC)上寻找光线,极度相互交互的颗粒。可以在LHC高能碰撞的非常前进的方向上产生此类颗粒,然后腐烂到Faser探测器内的可见颗粒,该颗粒将其放置在Atlas相互作用点的下游480 m,与梁碰撞轴对齐。 FASER还包括一个子检测器,Faser $ν$,旨在检测LHC碰撞中产生的中微子并研究其性质。在本文中,详细描述了FASER探测器的每个组件,以及实验系统的安装及其在2021年9月收集的宇宙射线和LHC Pilot Beam测试期间进行的调试。Faser将于2022年开始使用LHC碰撞数据,并将在2022年进行LHC碰撞数据,并将运行LHC 3。
FASER, the ForwArd Search ExpeRiment, is an experiment dedicated to searching for light, extremely weakly-interacting particles at CERN's Large Hadron Collider (LHC). Such particles may be produced in the very forward direction of the LHC's high-energy collisions and then decay to visible particles inside the FASER detector, which is placed 480 m downstream of the ATLAS interaction point, aligned with the beam collisions axis. FASER also includes a sub-detector, FASER$ν$, designed to detect neutrinos produced in the LHC collisions and to study their properties. In this paper, each component of the FASER detector is described in detail, as well as the installation of the experiment system and its commissioning using cosmic-rays collected in September 2021 and during the LHC pilot beam test carried out in October 2021. FASER will start taking LHC collision data in 2022, and will run throughout LHC Run 3.
