论文摘要
NA62实验是CERN SPS的固定目标实验。实验的主要目标是测量超稀有的kaon衰变的分支比率$ k^{+} \toπ^{+}ν\barν$。 NA62检测器还允许研究其他稀有的kaon衰变，并搜索MEV-GEV质量规模的非常弱的耦合颗粒。提出了新的抗0型hodoscope，并设计用于带有带电的光环颗粒进入衰减体积的事件。现在正在Cern组装。介绍了探测器设计，性能模拟以及带有宇宙射线和测试光束的单个元素的测量结果。委托和第一次数据捕获定于LS2 Long关闭结束后（2021年4月）。
The NA62 experiment is a fixed-target experiment at CERN SPS. The main goal of the experiment is to measure the branching ratio of the ultra-rare kaon decay $K^{+}\toπ^{+}ν\barν$. The NA62 detector allows also to study other rare kaon decays and to search for very weakly coupled particles of MeV-GeV mass-scale. The new ANTI-0 hodoscope is proposed and designed to veto events with charged halo particles entering the decay volume. It is now being assembled at CERN. The detector design, the performance simulation and the results of measurements with cosmic rays and test beams for the individual elements are presented. The commissioning and the first run of data-taking is scheduled for after the end of LS2 long shutdown (April 2021).
