摘要

supergd （Super Fine-Grained Detector）探测器是T2K实验中升级的近探测综合体ND280的关键元件。ND280升级旨在减少振荡测量中的系统误差，以提高对cp -奇数相位的实验灵敏度\({{\delta }_{{{\text{CP}}}}}\)。我们探讨了supergd探测器的现状，并报告了J-PARC在T2K中微子束中首次使用μ子中微子进行测量的结果。

The Near Neutrino SuperFGD Detector for the T2K Experiment

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.

期刊介绍： The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
