DUNE 3DST near detector

The Deep Underground Neutrino Experiment (DUNE) is an international project with primary physics objectives to measurement the CP violation in the neutrino sector, proton decay and supernova neutrino bursts. DUNE will use the liquid argon time projection chamber technology (LArTPC). DUNE will be composed of two neutrino detectors exposed to the world’s most intense neutrino beam. The near detector will be placed ~ 574 meters from the neutrino source at Fermilab. The far detector will be located ~1300 km away and ~1.4 kilometres underground at the Sanford Underground Research Facility (SURF) in South Dakota.

In this talk, we will focus on one of the DUNE near detector, a three-dimensional detector tracker called 3DST, which is a highly segmented plastic scintillator detector. With 3DST we expect to have a 4pi angle coverage for charged particles, as well as good energy and angular resolutions. Due to a fine granularity, 3DST is suitable for monitoring the beam profile and due to fast timing, it has great potential to measure neutron energy.
