摘要

ATLAS正向质子(AFP)探测器的目的是测量以非常小的角度散射的质子。AFP旨在研究衍射事件、独占产生和光子诱导的相互作用。2016年初安装了带有3D像素探测器的首支AFP手臂，并在当年晚些时候在特殊的低亮度运行中记录了跟踪器性能的数据。完整的双臂装置(在相互作用点的两侧)是在2016/2017年大型强子对撞机冬季关闭期间安装的。2017年，法新社参与了ATLAS高亮度数据的日常采集。此外，还进行了几次降低亮度的特殊运行。本文介绍了AFP检测器及其在2016年和2017年的性能。

ATLAS Forward Proton Detector

The purpose of the ATLAS Forward Proton (AFP) detector is to measure protons scattered at very small angles. AFP aims to study diffractive events, exclusive production and photon induced interactions. The first arm of AFP with 3D pixel detectors was installed in early 2016 and data to study the tracker performance were recorded later that year during special low luminosity runs. The full two-arm setup (on both sides of the interaction point) was installed during the 2016/2017 LHC winter shutdown. In 2017, AFP participated in the ATLAS high-luminosity data taking on a daily basis. In addition, several special runs with reduced luminosity were taken. This paper presents the AFP detector and its performance during 2016 and 2017.
