Description
The Deep Underground Neutrino Experiment (DUNE) has among its primary goals the determination of the neutrino mass ordering and the CP-violating phase in the PMNS mixing matrix.
An important component of the DUNE Near Detector complex is the System for On-Axis Neutrino Detection (SAND), which includes GRAIN, a novel Liquid Argon (LAr) detector designed to image neutrino interactions using scintillation light.
GRAIN is designed to provide a fine-grained reconstruction of neutrino interactions in LAr and to provide a control sample for neutrino events in the Near Detector's Liquid Argon Time Projection Chambers.
GRAIN uses an innovative optical readout system based on SiPM matrices coupled either to UV-Lenses or Coded Aperture masks to take "pictures" of the LAr scintillation light emission, eliminating the dependence on slow charge collection.
This contribution will discuss the current design of GRAIN, the development of its optical elements and image reconstruction algorithms, as well as the construction of a prototype demonstrator with two cameras with 256 pixels and cold readout electronics.
