A Development for Sterile Neutrino Search in Short Base Line Neutrino Oscillations

Outline of Final Research Achievements

Anomalies became clear as neutrino oscillations have been measured deeply. Sterile neutrino was introduced to solve the anomalies and some experiments were proposed to look for the sterile neutrinos. One of the strategies to solve the anomaly is to measure ultra-short base line neutrino oscillations; a neutrino source is installed right next to a neutrino detector. KamLAND is a low background neutrino detector that has an excellent achievement to measure the reactor neutrino oscillations and that solved the solar neutrino puzzle. A possibility to install the neutrino source in the KamLAND site was discussed and developed in this research.
