FastTracKer（FTK）是一种硬件专用处理器，在ATLAS实验中执行快速和精确的在线全轨迹重建，平均延迟为几十微秒。在利用现有最佳技术生产用于高占用条件下跟踪的最终系统之前，我们计划使用FTK硬件的现有原型在ATLAS环境中行使其功能。我们描述了“婴儿FTK”，由几个硬件元件实现的第一阶段的系统，并讨论了我们的计划，该系统发展成为一个全功能的FTK“垂直切片”覆盖一个小的投影楔的检测器。我们报告的性能和结构的“婴儿FTK”，包括像素/条带击中聚类（聚类夹层），击中组织和分布（EDRO）和联想记忆模式识别功能。我们还简要描述了未来可能的发展，包括增加轨道钳工。c 2011年欧洲核子研究中心，供ATLAS协作使用。由爱思唯尔公司出版。由2011年TIPP组委会负责甄选和/或同行评审。
The FastTracKer (FTK), a hardware dedicated processor, performs fast and precise online full track reconstruction at the ATLAS experiment, within an average latency of few dozens of microseconds. Before production of the final system for tracking in high-occupancy conditions with the best of available technology, we plan to use existing prototypes of the FTK hardware to exercise its functions in the ATLAS environment. We describe the “baby FTK”, consisting of a few hardware elements implementing the first stages of the system, and discuss our plans to grow the system into a full-functionality FTK “vertical slice” covering a small projective wedge of the detector. We report on the performances and structure of the “baby FTK”, including the pixel/strip hit clustering (clustering mezzanine), hit organization and distribution (EDRO) and the Associative Memory pattern recognition function. We describe briefly also the possible future evolution including the addition of the Track Fitter. c 2011 CERN, for the benefit of ATLAS Collaboration. Published by Elsevier BV.
