摘要
FASER 是一个新实验，旨在搜索新的轻弱相互作用长寿命粒子（LLPs）并研究 CERN LHC 对撞极前向区的高能中微子相互作用。实验装置位于 ATLAS 相互作用点下游 480 m 处，与束流碰撞轴对齐。FASER 探测器包括四个由硅微条探测器构成的相同径迹站。其中三个径迹站构成径迹谱仪，使 FASER 能够探测在装置内部衰变的 LLPs 的衰变产物，而第四个站用于中微子分析。该谱仪自 2021 年 3 月起安装在 LHC 设施中，而第四站尚未安装。FASER 将在 2022 年初 LHC 恢复运行时开始物理数据获取。本文描述了径迹谱仪的设计、建造和测试，包括机械结构、读出电子学、电源和冷却系统等相关组件。
