Description
T2K is a long-baseline experiment for the measurement of neutrino and antineutrino oscillations. The ND280 near detector at J-PARC plays a crucial role to minimise the systematic uncertainties related to the neutrino flux and neutrino-nucleus cross-sections.
ND280 has been recently upgraded with a new suite of sub-detectors: a high granularity target with 2 million optically-isolated scintillating cubes read out by wavelength shifting fibres and 55000 Multi-Pixel Photon Counters; two horizontal Time-Projection Chambers instrumented with resistive Micromegas and 6 panels of scintillating bars for precise time-of-flight measurements.
The new detectors were installed in 2023-2024. Results from the first data collected with a neutrino beam will be shown, and the performance of the detector will be highlighted: large acceptance for tracks produced at large angle, low threshold for pion and proton reconstruction, full kinematic measurement of neutrons and improved particle identification.
