• Resumen

  • This thesis investigates the detection of coherent elastic neutrinonucleus scattering (CEνNS), a challenging low-energy neutrino interaction. It evaluates various neutrino sources—reactor, spallation, and solar—and detector materials, highlighting the European Spallation Source (ESS) as a promising site. Key contributions include the development of a compact 4π neutron scatter camera with integrated optical imaging, and the design of GanESS, a highREGISTRO TELEMÁTICO-pressure noble gas time projection chamber optimized for CEνNS detection using argon, xenon, or krypton. First results with the Gaseous Prototype (GaP) show promising energy thresholds and performance. Detailed simulations using Garfield++ and COMSOL provide insights into electroluminescence behaviour and threshold estimation, although some non-linear detector responses at low E/p remain unresolved. Overall, this work establishes a robust foundation for CEνNS studies at spallation sources and advances detection technologies with broader implications for neutrino physics and rareevent searches.
