Abstract

The JSNS2(J-PARC Sterile Neutrino Search) at the J-PARC Spallation Neutron Source is designed to study neutrino oscillations over a 24-m short baseline. The collisions of a proton beams with a mercury target provide pions and their decayed muons at rest. The existence of the sterile neutrino is expected to be investigated by observing νμ→ νeoscillation through these events. The JSNS2inner detector is filled with 30 tons of an un doped liquid scintillator (LS) and 17 tons of a gadolinium-doped (Gd)LS, surrounded by 120 photomultiplier tubes (PMT). Because one of the most important tasks in the JSNS2experiment is keeping the state of the LS constantly, environmental factors such as temperature, pressure, humidity, and the level of the LS must be mentioned. For this purpose, we installed four sensors at the detector. In this paper, we introduce a way to get the signals from the four sensors by using LabVIEW and manage them. In particular, long-term collected data will be used for understanding the relations between the experimental results and the environmental factors.
