The T2K experiment is a second generation neutrino oscillation experiment using the existing Super-Kamiokande observatory as the main detector. The new Japanese nuclear physics facility being built at Tokai, on Japan's east coast, has a high-power 50 GeV proton synchrotron originally intended to produce beams for neutron scattering and high energy nuclear physics. The aim of T2K is to use this high-intensity proton beam to generate an intense muon neutrino beam aimed approximately at Super-Kamiokande (a slightly off-axis geometry is used to produce a more monochromatic beam).

The primary aim of the T2K experiment is to measure sin²2theta_23 to an accuracy of +0.01, the 2-3 mass squared difference to an accuracy of 10^-4 eV, and the as yet unmeasured mixing angle sin²2theta_13 to an accuracy of approximately 0.01 (depending on the values of other parameters). This performance is about an order of magnitude better than currently running experiments.

The T2K-UK Collaboration, consisting of groups from Imperial College, Lancaster, Liverpool, Queen Mary, RAL, Sheffield and Warwick, has recently been successful in attracting seedcorn funding from PPARC. The UK group will build the Electromagnetic Calorimeter (ECAL) for the Near Detector (ND280m), as well as the electronics and the associated readout system. CCLRC (RAL) engineers are leading the design of the target and beam dump. Physicists and engineers from Liverpool are leading the design and construction of the ECAL, which will be assembled at the nearby Daresbury Laboratory. Our group also has major commitments in core offline software development for the ND280m detector, and physics studies.
