Description
T2K is a long baseline neutrino oscillation experiment started in 2009. The neutrino beam produced at J-PARC (Japan Proton Accelerator
Research Complex) is observed by both a near detector (ND280) and a far detector (Super Kamiokande), to produce an oscillation measurement. The main goal of T2K is to measure the unknown mixing angle theta_13 by observing conversion from the muon-type neutrino to the electron-type neutrino. To achieve high sensitivity for this measurement, it is important to measure the neutrino beam flux and energy for each flavor of the neutrino at the near detector, located 280m from the neutrino production target. The FGDs (Fine-Grained Detector) compose main parts of the near detector complex. They consist of layers of scintillator bars and act as both a neutrino interaction target and as a tracking detector. We started data-taking in the winter of 2009/10. The performance and commissioning of the FGDs in the initial data taking is reported.
