Near detector complex for the T2K long base line experiment

The Tokai-2-Kamioka (T2K) project has been recently approved to search for the first signal of νe appearance in a conventional νμ beam, and to measure the θ13 neutrino mixing parameter. T2K sends a beam of neutrinos from the Japan Proton Research Complex(JPARC) to Super-Kamiokande with a baseline of 295 km using the Off-Axis beam technique. The neutrinos are measured in a near site, just after production, for flux normalization and background prediction. The design goals of the near detector for the T2K project are discussed.
