T2K run extension being studied
The T2K collaboration is considering the improvements in physics sensitivity, especially for CP violation, from an extension of the running time with beam power of ~1.3 MW. An Expression of Interest for the T2K extension was presented to the J-PARC PAC held January 13-15, 2016.
J-PARC Main Ring upgrade approved
A new facility in J-PARC to upgrade the Main Ring accelerator is approved. This facility will house a new power supply system with which the repetition rate of the Main Ring will be doubled―resulting in 750 kW beam power for T2K, with potential to exceed 1 MW.

Takaaki Kajita wins 2015 Nobel prize in physics
The Royal Swedish Academy of Sciences has announced that T2K collaboration member Takaaki Kajita will be awarded the 2015 Nobel prize in physics. Prof Kajita, Director of The Institute for Cosmic Ray Research (ICRR), University of Tokyo, shares the award with Prof Arthur McDonald (Queen’s University, CA) “for the discovery of neutrino oscillations, which shows that neutrinos…
T2K releases its first measurement of muon-antineutrino disappearance
T2K released its first measurement of muon-antineutrino disappearance in a seminar at the KEK High Energy Accelerator Research Organization on 18th May 2015. This result has been obtained from data taken from May 2014 – March 2015. During this time, T2K has been running with a beam composed mostly of muon antineutrinos, and 59.8 events…
J-PARC delivers 1×1021 protons on target to T2K

T2K sees its first event in antineutrino beam mode
T2K resumed data taking on 26 May 2014 after a 1-year shutdown caused by the hadron hall radiation accident. Many thanks are due to the J-PARC directorate and the staff members for their incredible effort over many months to make this possible! During the beamline commissioning, the first antineutrino beam at J-PARC (and the first…
