NA62实验的目的是在欧洲核子研究中心的超级质子同步加速器（SPS）上测量超稀有衰变K+箭π+ ν ν π分支比，精度为± 10%。NA62的触发系统由三个不同的级别组成，旨在选择在高束流率环境中感兴趣的物理事件。L0触发处理器（L0TP）是触发链的最低级别系统。它是使用可编程逻辑实现的硬件。NA62 L0TP系统的架构与高能物理实验中使用的现有系统相比是一种新方法。它是完全数字化的，基于探测器和L0TP板之间的标准千兆以太网通信。L0TP板是一种商业开发板，安装了可编程逻辑器件（FPGA）。在整个光束溢出期间，使用UDP协议将子检测器生成的基元异步发送到L0TP。L0TP在时间上重新排列来自七个不同来源的基元，并基于事件的特征（例如子检测器中的命中的能量、多重性和拓扑）执行数据选择。它保证最大延迟为1 ms。每个子检波器的最大输入速率约为10 MHz，而设计最大输出触发速率为1 MHz。这里给出了触发算法的描述。
The NA62 experiment is designed to measure the ultra-rare decay K+ arrow π+ ν ν̄ branching ratio with a precision of ∼ 10% at the CERN Super Proton Synchrotron (SPS). The trigger system of NA62 consists in three different levels designed to select events of physics interest in a high beam rate environment. The L0 Trigger Processor (L0TP) is the lowest level system of the trigger chain. It is hardware implemented using programmable logic. The architecture of the NA62 L0TP system is a new approach compared to existing systems used in high-energy physics experiments. It is fully digital, based on a standard gigabit Ethernet communication between detectors and the L0TP Board. The L0TP Board is a commercial development board, mounting a programmable logic device (FPGA). The primitives generated by sub-detectors are sent asynchronously using the UDP protocol to the L0TP during the entire beam spill period. The L0TP realigns in time the primitives coming from seven different sources and performs a data selection based on the characteristics of the event such as energy, multiplicity and topology of hits in the sub-detectors. It guarantees a maximum latency of 1 ms. The maximum input rate is about 10 MHz for each sub-detector, while the design maximum output trigger rate is 1 MHz. A description of the trigger algorithm is presented here.
