| Resumo: | Neutrinos have been the cause of different paradigm shifts in physics in the last hundred years, particularly with the discovery of neutrino oscillation. However, different open questions remain that are a natural door to new physics Beyond the Standard Model, such as the existence of CP violation or the origin of their mass. The DUNE experiment is a next-generation long-baseline reactor neutrino experiment that will measure the neutrino oscillation parameters with unprecedented precision, the CP-violating phase, the mass hierarchy and will probe different Beyond Standard Model proposals such as the existence of sterile neutrinos. Thanks to the most powerful neutrino beam in the world DUNE will collect an unmatched number of events, reducing the impact of statistical errors in the measured quantities. However, this means that systematic uncertainties must be constrained as well, which will require detectors with cutting-edge capabilities. The main objective of this thesis is the development of a new technological proposal for the high pressure argon-based TPC of DUNE, the ND-GAr, located in the near detector complex. This proposal must fulfill several requirements, such as the capability of providing T0 information inside the TPC, a high granularity readout, fine ns-level time stamping and high momentum resolution. |
