Description

DUNE is a leading-edge experiment for neutrino oscillation physics and is
currently under construction in the United States, between Fermilab, where
neutrino beam is generated, and the SURF underground laboratory, in South
Dakota, hosting the Far Detector at a depth of 4,850 mwe and at a baseline
of nearly 1,300 km. GRAIN (GRanular Argon for Interactions of Neutrinos) is
the Liquid Argon detector of SAND (System for On-Axis Neutrino Detection),
which is part of the DUNE Near Detector complex. SAND is expected to
significantly decrease uncertainties related to neutrino flux and cross-sections.
Additionally, SAND will have the capacity to monitor the beam stability, and to
investigate various neutrino interactions models, constraining at the same time
nuclear effects. A key element of SAND is GRAIN, which will serve as a Liquid
Argon target for detecting neutrinos and low-energy particles, ensuring crosscalibration
with the other Near Detector components. This poster will discuss
the novel GRAIN system designed for reconstructing charged particle tracks in
LAr. It is based on the detection of scintillation light by an optical system
optimised for the Vacuum Ultra-Violet, coupled to SiPM matrices. Another
research topic that will be described concerns the development of a cryogenic,
1024-channel ASIC, able to read 32x32 SiPM matrices.
