The T2K project focuses on long baseline neutrino oscillation, and attempts to measure the third type of neutrino oscillation.

Approximately 400 physicists and 2000 engineers have combined forces to fire a beam of muon-type neutrinos 295 km across Japan, from J-PARC in Tokai to Kamioka. The beam is received by the Super-Kamiokande detector, where scientists attempt to measure the oscillation between muon and tau neutrinos. However neutrinos react very weakly and most are not captured by the detector, so continue into space. Due to this, the detector has to be very large.

In the future, upgrades to T2K could lead to measuring the CP violation by comparing oscillations of neutrinos to those of antineutrinos. These developments could aid the search for an explanation as to why we don't see equal amounts of matter and antimatter. The project will also use MPPCs (Multi-pixel Photon Counters) and is therefore helping to develop these.
