Description
Summary:An upgrade of the long baseline neutrino experiment T2K near detector ND280 is currently being designed. The upgrade program includes the development a new highly granular fully active scintillator neutrino detector as a neutrino target. The baseline concept of the detector represents an array of about 2×106 small scintillator cubes each of 1 cm3. The 3D signal readout from each cube is provided by three orthogonal 1.0 mm Kuraray Y11 multiclad WLS fibers read out by SiPMs. A small prototype of the detector assembled of 125 cubes was tested in a beam of charged particles as well as with cosmic muons. Obtained parameters of the prototype are reported in this paper.
