JSNS 2（在J-PARC散裂中子源上的J-PARC无菌中微子搜索）实验旨在搜索J-PARC 24米短基线上的中微子振荡。JSNS 2内部探测器充满了17吨装载钆（Gd）的液体闪烁体（LS），在中间γ-捕集器中还有另外31吨卸载的液体闪烁体和光学分离的外部体积。共有120个10英寸光电倍增管观察闪烁的光子，每个模拟波形由闪存模数转换器存储。我们详细介绍了数据采集、处理和数据质量监测系统。我们还提出了两种不同的触发逻辑，分别用于光束和自触发。
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 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.
