Abstract

The Fast Tracker is an integral part of trigger upgrade program for the ATLAS experiment. At LHC Run 2, which started operations in June 2015 at a center of mass energy of 13 TeV, the luminosity could reach up to 2•1034 cm−2 s−1 and an average of 40-50 simultaneous proton collisions per beam crossing will be expected. The higher luminosity demands a more sophisticated trigger system with increased use of tracking information. The FTK is a highly-parallel hardware system that rapidly finds and reconstructs tracks in the ATLAS inner-detector at the triggering stage. This paper focuses on the Mezzanine Board that is input module of the entire FTK system. The functions of this board are: receive the pixel and micro-strip data from the ATLAS Silicon read-out drivers, perform clustering, and forward the data to its mother board. Mass production and quality control tests of Mezzanine Boards were completed, and staged installation and commissioning are ongoing. Details of its functionality, mass production, quality control tests, and installation are reported.

在ATLAS上输入快速跟踪器的mezz卡

快速跟踪器是ATLAS实验触发器升级计划的一个组成部分。在2015年6月开始运行的LHC Run 2，其质能中心为13 TeV，光度可达2•1034 cm−2 s−1，平均每束穿越将同时发生40-50次质子碰撞。更高的亮度要求更复杂的触发系统，增加跟踪信息的使用。FTK是一种高度并行的硬件系统，可以在触发阶段快速发现和重建ATLAS内部探测器的轨迹。本文重点研究了整个FTK系统的输入模块Mezzanine Board。该板的功能是:接收来自ATLAS Silicon读出驱动的像素和微带数据，进行集群处理，并将数据转发给母板。meanine Boards已完成批量生产和质量控制测试，并正在进行阶段安装调试。报告了其功能、批量生产、质量控制测试和安装的细节。
