The Sterile Neutrino Search at the J-PARC Spallation Neutron Source (JSNS$^2$) experiment aims 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 of the photomultiplier tubes, 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 2020 June. In this paper, we present a description of the assembly and installation of the SCMS and its performance.

JSNS2 的慢速控制和监控系统

J-PARC 散裂中子源 (JSNS$^2$) 实验中的无菌中微子搜索旨在使用静止时 μ 子衰变的中微子束搜索无菌中微子振荡。JSNS$^2$ 探测器包含 17 吨 0.1$\%$ 钆 (Gd) 负载液体闪烁体 (LS) 作为中微子目标。探测器建设于2020年春季完成。实施慢控监测系统（SCMS），对探测器运行状态和环境条件进行可靠控制和快速监测。如果任何被监控的参数超过预设的可接受范围，它就会发出警报。SCMS 监测光电倍增管的高压、检测器中的 LS 水平、可能的 LS 溢出和泄漏、检测器中的温度和气压、实验大厅的湿度、以及填充和提取过程中的 LS 流量。在 2020 年 6 月探测器和 SCMS 成功调试后，使用中微子束进行了最初 10 天的数据采集。在本文中，我们介绍了 SCMS 的组装和安装及其性能。
