J-PARC Neutrino Beamline and 1.3 MW Upgrade
Abstract
J-PARC neutrino beamline has been operated since 2009. Until May 2018, the maximum beam power achieved was ~500 kW. In future, the beam power will be upgraded to 1.3 MW. After the stable operation in late 2020s, we can accumulate ~30 x 1020 POT data per year. It is almost the same number as total POT accumulated in recent 10 years. The upgrade plan of the Main Ring as well as the neutrino beamline is reported.
