论文摘要

JSNS $^2 $实验的目的是使用Muon衰变中的中微子束搜索无菌中微子振荡。 JSNS $^2 $检测器包含17吨0.1 \％Gadolinium（GD）的液体闪光灯（LS）作为中微子目标。探测器的构建于2020年春季完成。实施了缓慢的控制和监视系统（SCM），以可靠控制和快速监控检测器操作状态和环境条件。如果任何受监视参数超过预设可接受的范围，则会发出警报。 SCMS监测光电倍增管（PMTS）的高压（HV），检测器中的LS水平，可能的LS溢流和泄漏，检测器中的温度和气压，实验厅的湿度以及在填充和提取过程中LS流量的湿度。在2020年6月成功调试检测器和SCM之后，完成了最初的10天与中微子光束进行数据获取。在本文中，我们介绍了SCM的组装和安装及其性能的描述。

The JSNS$^2$ experiment is aimed to search for sterile neutrino oscillations using a neutrino beam from muon decays at rest. The JSNS$^2$ detector contains 17 tons of 0.1\% gadolinium (Gd) loaded liquid scintillator (LS) as a neutrino target. Detector construction was completed in the spring of 2020. A slow control and monitoring system (SCMS) was implemented for reliable control and quick monitoring of the detector operational status and environmental conditions. It issues an alarm if any of the monitored parameters exceed a preset acceptable range. The SCMS monitors the high voltage (HV) of the photomultiplier tubes (PMTs), the LS level in the detector, possible LS overflow and leakage, the temperature and air pressure in the detector, the humidity of the experimental hall, and the LS flow rate during filling and extraction. An initial 10 days of data-taking with a neutrino beam was done following a successful commissioning of the detector and SCMS in June 2020. In this paper, we present a description of the assembly and installation of the SCMS and its performance.
