Description
T2K is a long-baseline neutrino experiment based in Japan. Its Near Detector complex is undergoing a significant update; in particular, part of the ND280 detector is being replaced by three new subdetectors: SFGD, two HA-TPCs, a TOF.
The latter was completely designed, assembled, tested and commissioned by the DPNC of UniGe. The commissioning is still ongoing and has included several activities: assembling and testing of the hardware (scintillator bars read out by SiPMs, a digitizer with excellent time resolution, a Slow Control system), implementation of the DAQ and SC systems, software development, data analysis. The detector is already installed in Japan in almost all its components and has been taking cosmic data as well as neutrino beam data.
In this poster we present preliminary results about the TOF capabilities and first analyses of the data taken in particular in December 2023, which are going to be interfaced with the other detectors in the upcoming months.
