2015年12月完成了一项测试轻子味普适性（LFU）的实验，该实验使用正电子和μ子（J-PARC E36）对两体K介子衰变的衰变宽度比进行精确测量。实验是在日本质子加速器研究中心（J-PARC）的K1.1BR束线上进行的。我们开发并构建了一个数据采集（DAQ）系统，为这个实验。DAQ系统必须集成几种传统的和最新类型的读出系统，以满足实验要求。我们使用了一个事件同步的方法，通过分布的事件标识号，称为事件标签，和一个共同的网络集成不同类型的读出系统。整个DAQ在实验数据采集期间非常稳定，在250 Hz的触发率下具有10%的死区时间。
An experiment to test Lepton Flavor Universality (LFU) using a precise measurement of the decay width ratio of the two-body kaon decays with a positron and a muon (J-PARC E36), completed data-taking in December 2015. The experiment was performed on the K1.1BR beam-line at the Japan Proton Accelerator Research Complex (J-PARC). We developed and constructed a data acquisition (DAQ) system for this experiment. The DAQ system had to integrate several traditional and also recent types of readout systems to satisfy the experimental requirements. We used an event synchronization method by distributing the event identifying number, called the event-tag, and a common network to integrate the different types of readout systems. The entire DAQ was very stable during the experiment data-taking with 10 % dead-time at a trigger rate of 250 Hz.
