快速跟踪器（FTK）是大型强子对撞机（LHC）ATLAS探测器触发升级计划的一个组成部分。随着LHC的光度接近其设计水平1034 cm−2s−1，由于每个束团交叉的多重相互作用的膨胀，带电粒子跟踪所带来的组合问题变得越来越困难。FTK是一个高度并行的硬件系统，旨在为在线触发系统提供真实的时间内横向动量大于1 GeV的高质量径迹。FTK系统的设计，基于先进技术的混合，以及预期的物理性能将被介绍。
The Fast Tracker (FTK) is an integral part of the trigger upgrade program of the ATLAS detector at the Large Hadron Collider (LHC). As the LHC luminosity approaches its design level of 1034 cm−2s−1, the combinatorial problem posed by charged particle tracking becomes increasingly difficult due to the swelling of multiple interactions per bunch crossing. The FTK is a highly-parallel hardware system intended to provide high-quality tracks with transverse momentum above 1 GeV in real time for online trigger system. The FTK system's design, based on a mixture of advanced technologies, and the expected physics performance will be presented.
