Description
The T2K experiment is a long-baseline neutrino oscillation experiment in Japan. A muon (anti-)neutrino beam produced at J-PARC is detected at the near detector ND280 and the far detector Super-Kamiokande (SK). The ND280 detects neutrino interaction candidates before oscillation to predict the neutrino flux in SK and constrain neutrino-nucleus interaction models.
To reduce systematic uncertainties, a new detector Super-FGD was installed in ND280 in October 2023. It consists of about 2 million 1 cm^3 scintillator cubes and fibers inserted in the cubes in three directions. Signals detected by photo detectors attached to the fiber ends are digitized and transmitted in custom electronics boards. A DAQ system was developed to read out this data in a way that minimizes system complexity while also accepting data at a high rate. We report on this DAQ system which was integrated to the conventional ND280 DAQ system successfully and detected the first neutrino candidate event in December 2023.
