A Highly Granular Electromagnetic Calorimeter Concept for the DUNE Near Detector — •Lorenz Emberger1, Eldwan Brianne2, and Frank Simon1 — 1Max-Planck-Institut für Physik — 2DESY
The near detector (ND) of the Deep Underground Neutrino Experiment (DUNE) will play an important role in the search of CP violation in the neutrino sector. Additionally, as a standalone complex, it will be an excellent laboratory to study a wide range of neutrino interactions. The ND design study consists of three independent sub-detectors, placed downstream of the neutrino production target. One of these detectors, a Multi Purpose Detector (MPD), consists of a high pressure gaseous Argon time projection chamber (TPC), surrounded by an electromagnetic calorimeter (ECAL) and a muon system. One key aspect of the ECAL is the reconstruction of neutral particles such as neutral pions and neutrons invisible in the TPC. We present a concept study of the MPD system featuring a highly granular electromagnetic calorimeter inspired by the SiPM-on-Tile technology developed by the CALICE collaboration. First studies of the reconstruction of neutral pions decaying into two photons inside the TPC will be covered. Additionally, we will touch on background studies carried out in the full MPD geometry.
