摘要

在2015年6月开始运行的LHC Run 2上，质心能量为13 TeV，峰值亮度超过2×1034 cm−2s−1,LHC平均同时产生60次碰撞。更高的亮度要求更复杂的触发系统，增加跟踪信息的使用。快速跟踪器(FTK)是ATLAS实验触发器升级计划的一个组成部分。FTK是一个使用asic和fpga的大规模并行硬件系统。它以高达100 kHz的全Level-1可接受速率工作，并为pT > 1GeV的所有轨道提供完整的事件轨道重建，平均延迟低于100 μs。FTK输入夹层板是FTK系统的输入接口，对ATLAS内部探测器中的所有集群进行全重构。这些程序报告了FTK输入夹层板功能的细节及其安装和调试状态。

Input Mezzanine Board for the Fast Tracker(FTK) at ATLAS

At LHC Run 2, which started operation in June 2015 at a center-of-mass energy of 13 TeV, the peak luminosity has exceeded 2×1034 cm−2s−1 and the LHC produce an average of 60 simultaneous collisions. The higher luminosity demands a more sophisticated trigger system with increased use of tracking information. The Fast Tracker (FTK) is an integral part of the trigger upgrade program for the ATLAS experiment. The FTK is a massively parallel hardware system using ASICs and FPGAs. It operates at the full Level-1 accepted rate of up to 100 kHz and provides full event track reconstruction for all tracks with pT > 1GeV with an average latency below 100 μs. The FTK Input Mezzanine Board is the input interface of the FTK system which performs full reconstruction of all clusters in the ATLAS Inner Detector. These proceedings report details of the functionality of the FTK Input Mezzanine Board and its status of installation and commissioning.
