J-Parc散裂中子源(JSNS)实验中的不孕中微子搜索旨在利用静止的Muon衰变产生的中微子束来搜索不孕中微子振荡。JSNS探测器包含17吨装载了0.1 Gd(Gd)的液体闪烁体(LS)作为中微子目标。探测器的建造于2020年春季完成。为了可靠地控制和快速监测探测器的运行状态和环境条件，实施了慢速控制和监测系统(SCMS)。如果监测到的任何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电压、检测器中的LS电平、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。在探测器和SCMS于2020年6月成功调试后，利用中微子束进行了最初10天的数据采集。本文介绍了SCMS的组装、安装及其性能。
The Sterile Neutrino Search at the J-PARC Spallation Neutron Source (JSNS) experiment aims to search for sterile neutrino oscillations using a neutrino beam from muon decays at rest. The JSNSdetector contains 17 tons of 0.1gadolinium (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.
