摘要:

高能物理实验中μ子轨道的在线重建是一项高要求的任务,通常使用可编程逻辑板(如FPGA)执行。在准实时环境中执行复杂的分析算法,以在通常富含噪声的环境中识别、选择和重建局部轨迹。针对漂移管探测器的μ子重构问题,提出了一种基于人工神经网络和解析方法相结合的局部触发信号产生方法。所提出的算法利用神经网络来解决否则计算昂贵的分析任务的唯一识别的相干信号和几何模糊的去除。所提出的方法部署在最先进的FPGA上,并通过仿真和从宇宙射线收集的数据评估其性能。

英文摘要:

The online reconstruction of muon tracks in High Energy Physics experiments is a highly demanding task, typically performed with programmable logic boards, such as FPGAs. Complex analytical algorithms are executed in a quasi-real-time environment to identify, select and reconstruct local tracks in often noise-rich environments. A novel approach to the generation of local triggers based on an hybrid combination of Artificial Neural Networks and analytical methods is proposed, targeting the muon reconstruction for drift tube detectors. The proposed algorithm exploits Neural Networks to solve otherwise computationally expensive analytical tasks for the unique identification of coherent signals and the removal of the geometrical ambiguities. The proposed approach is deployed on state-of-the-art FPGA and its performances are evaluated on simulation and on data collected from cosmic rays.
