Outline of Final Research Achievements |
Upgrades to the hardware and analysis software of Super-Kamiokande, the far detector and integral component of the T2K long-baseline neutrino oscillation experiment, have been performed to enable both stable operation of the detector and to reduce systematic uncertainties associated with measurements of neutrino interaction times, vertices, and energies. Using these improvements and overcoming shutdowns due to an earthquake in 2011 and an accident in 2013, T2K has made the world's first observation of oscillation-induced electron neutrino appearance. Knowledge and experience gained throughout this work will be utilized in future studies towards the realization of the next generation of neutrino experiments.
