概要 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-loaded liquid scintillator (LS) and both the intermediate
$\gamma$-catcher and the optically separated outer veto are filled with
un-loaded LS. Optical photons from scintillation are observed by 120
Photomultiplier Tubes (PMTs). A total of 130 PMTs for the JSNS2 experiment were
both donated by other experiments and purchased from Hamamatsu. Donated PMTs
were purchased around 10 years ago, therefore JSNS$^{2}$ did pre-calibration of
the PMTs including the purchased PMTs. 123 PMTs demonstrated acceptable
performance for the JSNS$^{2}$ experiment, and 120 PMTs were installed in the
detector.
