Status of the T2K 280m Near Detector

Understand

The Tokai-to-Kamioka (T2K) long-baseline neutrino-oscillation experiment is being prepared for start of operations in Fall 2009.

• The purpose of T2K is to measure the oscillation parameters from an intense muon neutrino beam.
• In order to make precision measurements of muon neutrino disappearence a new detector complex (ND280) will be used to identify the profile and composition of the neutrino beam near its production site.
• ND280 will also be used to study important background processes in the measurement of an electron neutrino appearance signal at Super-K.
