Abstract: ANAIS-112 es un experimento de detección directa de materia oscura (MO) ubicado en el Laboratorio Subterráneo de Canfranc. Su objetivo es confirmar o refutar el controvertido resultado del experimento DAMA/LIBRA, que observa una modulación anual en su ritmo de detección compatible con la esperada para MO en el halo galáctico. ANAIS-112 no ha podido observar esta modulación. ANAIS+ es un proyecto en fase de I+D que buscar mejorar la sensibilidad de ANAIS-112. Este trabajo se basa en el diseño y la simulación de un posible prototipo de ANAIS+ empleando un sistema de blindaje para detectores de centelleo de NaI basado en argón líquido. Para ello se han empleado ROOT y Geant4 y se han simulado las contribuciones más importantes al fondo de ANAIS-112. Una vez obtenidos los resultados se han analizado cada una de las contribuciones al fondo y se ha construido un modelo de fondo razonable.
ANAIS-112 is a direct detection dark matter (DM) experiment located in Laboratorio Subterráneo de Canfranc. It´s objective is to confirm or refute the controversial result of the DAMA/LIBRA experiment, which observed an annual modulation in it´s detection rate consistent with that expected for DM in the galactic halo. ANAIS-112 has not been able to observe this modulation. ANAIS+ is an R&D; project that seeks to improve ANAIS-112 sensitivity. This work is based on the design and simulation of a possible ANAIS+ prototype using a shielding system for NaI scintillation detectors based on liquid argon. For this purpose, ROOT and Geant4 were used, and the most relevant contributions from ANAIS-112 background have been simulated. Once the results were obtained, each of the contributions to the background was analyzed and a reasonable background model was made.
