Description
NEOS is an experiment to search for a light sterile neutrino from a reactor core at a short baseline. Electron antineutrinos from the reactor are measured by a 1,000 liter volume of gadolinium doped liquid scintillator detector. The detector was deployed at a 24-m distance from a 2.8 gigawatt-thermal-power reactor core in the tendon gallery of the Hanbit-5 reactor containment. The measurement was conducted for about 2 years, including a full reactor operation cycle and the reactor maintenance periods before and after. Sensitivity of finding the neutrino mass-squared-split and the mixing angle for the active-to-sterile neutrino oscillation using rate and shape analysis has been studied, considering the statistical and systematic uncertainties of NEOS-II.
