The T2K Experiment
- The T2K project, due to begin data-taking in 2009, has the primary goal of measuring for the first time a third type of neutrino mixing, which would result in the appearance of electron-type neutrinos from a beam of muon-type neutrinos after they have travelled 295 km across Japan.
T2K is the first of the “next generation” of oscillation experiment designed with very high intensity neutrino beams. The T2K “far detector” is the tried-and-tested Super-Kamiokande 50kt water Cherenkov detector, and the beam is optimised to enhance the oscillation signal and to suit the energies at which Super-Kamiokande can best measure the incoming neutrino type and energy.
Both the beam and the way its neutrinos interact with water must be very well understood for an oscillation discovery to be made, and a “near detector” will be positioned a few hundred metres from the beam origin to make measurements on the beam before it starts oscillating. UK institutes are involved in many aspects of T2K construction from the beam onwards, and in particular we are building a system of electromagnetic calorimeters for the near detector.
