论文摘要

JSNS $^{2} $（J-PARC散布中微子中微子搜索中微子搜索）实验旨在在J-Parc的24 m短基线上搜索中微子振荡。 JSNS $^{2} $内部检测器装有17吨Gadolinium（GD）负载的液体闪烁体（LS），并在中间$γ$ catcher和光学分离的外部兽医体积中附加了31吨卸载的LS。总共120个10英寸的光电倍增管观察了闪烁的光光子，并且每个模拟波形都用闪光类似物对数字转换器存储。我们介绍数据采集，处理和数据质量监视系统的详细信息。我们还提出了两个不同的触发逻辑，这些逻辑是为光束和自触发的。

The JSNS$^{2}$ (J-PARC Sterile Neutrino Search at J-PARC Spallation Neutron Source) experiment aims to search for neutrino oscillations over a 24 m short baseline at J-PARC. The JSNS$^{2}$ inner detector is filled with 17 tons of gadolinium(Gd)-loaded liquid scintillator (LS) with an additional 31 tons of unloaded LS in the intermediate $γ$-catcher and an optically separated outer veto volumes. A total of 120 10-inch photomultiplier tubes observe the scintillating optical photons and each analog waveform is stored with the flash analog-to-digital converters. We present details of the data acquisition, processing, and data quality monitoring system. We also present two different trigger logics which are developed for the beam and self-trigger.
