NA62实验的目的是研究极端罕见的K+ ？π+vv，并以10%的精度测量其分支比。为了做到这一点，来自欧洲核子研究中心SPS的高强度光束被用来产生带电的介子，其衰变产物被安装在60米衰变区域的许多探测器检测到。NA62数据采集系统（DAQ）采用多级触发系统；在Level0 （L0）触发决定之后，pc场读取来自大约60个源的1 MHz数据速率，然后构建部分事件，然后通过一系列Level1 （L1）算法来进一步降低触发率。通过此级别的事件以100 KHz的速率与丢失的更大的数据源（~400个源）一起完成。DAQ是围绕一个高性能以太网网络建立的，该网络将探测器连接到一个由30台服务器组成的集群。在对系统设计的总体描述和允许达到所需性能和功能的主要实现选择之后，本文描述了DAQ在2017年数据采集期间的总体行为。最后，对未来可能应用于该系统的改进和升级进行了展望。
The aim of the NA62 experiment is to study the extreme rare kaon decay K+ ? π+vv and to measure its branching ratio with a 10% accuracy. In order to do so, a very high intensity beam from the CERN SPS is used to produce charged kaons whose decay products are detected by many detectors installed along a 60 m decay region. The NA62 Data Acquisition system (DAQ) exploits a multi-level trigger system; following a Level0 (L0) trigger decision, 1 MHz data rate from about 60 sources is read by a PC-farm, the partial event is built and then passed through a series of Level1 (L1) algorithms to further reduce the trigger rate. Events passing this level are completed with the missing, larger, data sources (~400 sources) at the rate of 100 KHz. The DAQ is built around a high performance ethernet network interconnecting the detectors to a farm of 30 servers. After an overall description of the system design and the main implementation choices that allowed to reach the required performance and functionality, this paper describes the overall behaviour of the DAQ in the 2017 data taking period. It then concludes with an outlook of possible improvements and upgrades that may be applied to the system in the future.
