J-PARC Nu Beam Power Exceeds 400 kW!
The J-PARC neutrino beam, which provides neutrinos and antineutrinos for the T2K experiment, has exceeded 400 kW beam power. A new Main Ring accelerator tune allowed the beam power to exceed the 400 kW threshold on May 20, and the T2K beam ran stably above 400 kW from May 23 until May 27, when the…
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.
Koichiro Nishikawa and members of T2K Collaboration awarded Breakthrough Prize
Dr Koichiro Nishikawa and the members of the T2K collaboration have been awarded the prestigious Breakthrough Prize for Fundamental Physics, for their role in the discovery and study of neutrino oscillation. The prize, presented by the Breakthrough Prize Foundation, was awarded “for the fundamental discovery of neutrino oscillations, revealing a new frontier beyond, and possibly…
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
Today (March 26, 2015) at 15:25 the J-PARC accelerator achieved the milestone of delivering 1×1021 protons on target to T2K. Many thanks are due to the J-PARC directorate and the staff members for their outstanding work to make this possible ! The protons are produced by J-PARC in Tokai on the east coast of Japan.…
