Abstract
NEOS intends to understand the short-distance behavior of reactor neutrino oscillation. The detector has been obtaining about 2,000 inverse beta decay (IBD) events on daily base, since its performance was stabilized in September 2015. We present the geometry, the structure, and the current output of NEOS detector. The design of detector and the recipe of liquid scintillator mixture will be introduced, which were well set up enough to reduce the level of background. The signal-to-background ratio reached over 20. Including adjustment procedures for reconstruction, we will show the energy resolution of the detector and the energy calibration with GEANT4 simulation.
