摘要

Abstract—

The SuperFGD (Super Fine-Grained Detector) detector is a key element of the upgraded near detector complex ND280 in the T2K experiment. The ND280 upgrade is aimed at reducing systematic errors in oscillation measurements to increase the experimental sensitivity to the CP-odd phase \({{\delta }_{{{\text{CP}}}}}\) . We explore the current status of the SuperFGD detector and report results of the first measurements using muon neutrinos in the T2K neutrino beam in J-PARC.
