ATLAS Level-1 Muon Barrel触发器是大型强子对撞机ATLAS实验第一阶段事件选择的主要元件之一。1级系统的挑战是减少事件发生率从40 MHz的碰撞率的一个因素103，使用简单的算法，可以在高度并行的定制电子执行的延迟的顺序为1？S. 1级μ子的输入级由一组处理器组成，这些处理器接收来自专用探测器（桶中的电阻板室）的全粒度数据。该算法的第一阶段直接在检测器上执行，而最后阶段通过所谓的检测器外电子设备在安装在计数室中的板中执行。触发算法在固定的延迟内执行，其实时输出是通过一组可编程pT阈值的μ子候选者的多样性，以及它们的拓扑信息。探测器系统和触发电子器件的设计目的是实现安全的束流交叉识别。为了优化设计工作量和成本，触发系统还集成了探测器的读出，其对时间分辨率和整体数据带宽有自己的要求。我们提出了详细的功能要求的一级μ子桶系统，它的体系结构，实现和建设。
The ATLAS Level-1 Muon Barrel Trigger is one of the main elements of the first stage of event selection of the ATLAS experiment at the Large Hadron Collider. The challenge of the Level-1 system is a reduction of the event rate from a collision rate of 40 MHz by a factor 103, using simple algorithms that can be executed in highly parallel custom electronics with a latency of the order of 1 ?s. The input stage of the Level-1 Muon consists of an array of processors receiving the full granularity of data from a dedicated detector (Resistive Plate Chambers in the Barrel). This first stage of the algorithm is performed directly on-detector, while the final stage is performed in boards mounted in the counting room, by the so-called off-detector electronics. The trigger algorithm is executed within a fixed latency, its real-time output is the multiplicity of muon candidates passing a set of programmable pT thresholds, and their topological information. The detector system and the trigger electronics are designed to achieve a safe bunch-crossing identification. In order to optimize design effort and cost, the trigger system integrates also the readout of the detector, with its own requirements on time resolution and overall data bandwidth. We present the detailed functional requirements of the Level-1 Muon Barrel system, its architecture, implementation and construction.
