Abstract

The superFGD (sFGD), a scintillator detector, has been chosen as the target for neutrino in the T2K near detector upgrade. Its design enables nearly 4π coverage for neutrino interactions, leading to lower energy thresholds and reduced systematic errors in the experiment. The sFGD is assembled of optically-isolated scintillators measuring 1 × 1 × 1 cm3, it ensures the nessary spatial and energy resolution to minimize uncertainties in future T2K runs. With close to two million cubes assembled into a volumn of 1920 × 560 × 1840 mm3, the sFGD is a significant advencement. A prototypeconsisting of 4×4×3 cubes was studied using cosmic rays. The sFGD prototype, consisting of 48 cubes, was instrumented. We also present the results of the GEANT4 simulation of this prototype. Cosmic ray muon tracks crossing this prototype were simulated by the CRY generator. The results on angular distribution and energy deposition are studied at Tokai (36°27'42.8’N 140°35'57.7’E) and are presented in this paper.
