High-intensity particle beams provide a significant challenge to DAQ systems, especially in complex architectures reading out many sensors. The MUonE experiment has been conducting beam tests using the M2 muon beam at CERN, with in-spill intensity of 5 × 10⁷ muons/s, using tracking modules equipped with silicon strip sensors and a module readout bandwidth of 5 Gb/s. A pilot run has been performed in late summer 2023, incorporating several such modules arranged in three tracking stations and a prototype of an electromagnetic calorimeter connected to a triggerless readout system. Limits on processing and data storage will necessitate online event selection to be implemented in hardware, on state-of-the-art AMD-Xilinx UltraScale+ FPGAs. The status and plans of the MUonE DAQ operation will be presented, outlining a general purpose platform for online event selection, from simple occupancy cuts, to track reconstruction, vertexing, and particle identification.

MUonE DAQ：40 MHz 硬件中的在线轨迹查找和事件选择

高强度粒子束给 DAQ 系统带来了重大挑战，特别是在读取许多传感器的复杂架构中。 MUonE实验一直在CERN使用M2μ子束进行束流测试，泄漏强度为5×10 ⁷ μ子/秒，使用配备硅条传感器和模块读出带宽为5Gb/s的跟踪模块。试点运行已于 2023 年夏末进行，其中包含布置在三个跟踪站中的多个此类模块以及连接到无触发读出系统的电磁量热计原型。由于处理和数据存储的限制，在线事件选择必须在最先进的 AMD-Xilinx UltraScale+ FPGA 上的硬件中实现。将介绍 MUonE DAQ 操作的状态和计划，概述用于在线事件选择的通用平台，从简单的占用削减到跟踪重建、顶点和粒子识别。
