J-PARC Neutrino Beamline and 1.3 MW Upgrade
Yuichi Oyama
TL;DR
This paper discusses the upgrade of the J-PARC neutrino beamline to 1.3 MW, enabling significantly increased data collection for neutrino research starting in the late 2020s.
Contribution
It presents the detailed upgrade plan for the J-PARC beamline and Main Ring to achieve higher power and data accumulation capabilities.
Findings
Beam power increased from 500 kW to 1.3 MW.
Projected data collection of ~30 x 10^20 POT annually.
Enhanced stability and performance of the upgraded beamline.
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 10^20 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.
