Descripción del proyecto THE NATURE OF DARK MATTER, THAT COMPOSES 27% OF THE UNIVERSE IS ONE OF THE BIGGEST UNANSWERED QUESTIONS IN MODERN PHYSICS. THE DARK MATTER BARELY INTERACTS WITH ORDINARY MATTER MAKING THEIR DETECTION EXTREMELY CHALLENGING. ANOTHER UNSOLVED PROBLEM IN PHYSICS IS THE STRONG-CP PROBLEM, THE THEORY PREDICTS A VIOLATION OF CHARGE-PARITY SYMMETRY IN STRONG INTERACTIONS, WHICH HAS NOT BEEN OBSERVED EXPERIMENTALLY. THE MOST COMPELLING SOLUTION TO THE STRONG-CP PROBLEM WAS PROPOSED BY PECCEI AND QUINN BY THE INTRODUCTION OF A NEW GLOBAL AND AXIAL SYMMETRY, WHEN THIS SYMMETRY IS SPONTANEOUSLY BROKEN A NEW PARTICLE APPEARS, THE AXION. AXION PROPERTIES ARE PARTICULARLY APPEALING BECAUSE THEY SHOULD BARELY INTERACT WITH MATTER, THEREFORE AXIONS CAN SOLVE THE STRONG-CP PROBLEM AND AT THE SAME TIME THE DARK MATTER PROBLEM. THE DISCOVERY OF THE ELUSIVE AXION COUNTS ON NEW GENERATION HELIOSCOPES, LOOKING FOR SOLAR AXIONS, IN WHICH THE IAXO EXPERIMENT STANDS OUT. IAXO REQUIRES ULTRA-LOW BACKGROUND X-RAY DETECTORS OPERATING AT SURFACE LEVEL. CURRENT STUDIES POINT OUT THAT THE STATE-OF-THE-ART ON LOW BACKGROUND TECHNIQUES IS LIMITED BY COSMIC-RAY INDUCED EVENTS. HIGH ENERGY COSMIC NEUTRONS ARE PARTICULARLY DANGEROUS BECAUSE THEY CANNOT BE EFFICIENTLY SHIELDED OR TAGGED WITH COMPACT ENOUGH SYSTEMS COMPATIBLE WITH THE EXPERIMENTS GEOMETRICAL CONSTRAINTS. ON THE OTHER HAND, IAXO HAVE THE CAPABILITIES TO ENHANCE THE HELIOSCOPE TECHNIQUE, MAKING POSSIBLE THE DETECTION OF HIGH ENERGY (5.5 MEV) SOLAR AXIONS AS WELL AS GENERATED IN SUPERNOVA (SN) EXPLOSIONS. HOWEVER, THIS WOULD REQUIRE THE DEVELOPMENT OF A DEDICATED GAMMA-RAY DETECTOR IN THE 5-250 MEV ENERGY RANGE.THE GOAL OF THIS PROJECT IS THE DEVELOPMENT OF A NEW DETECTOR BASED ON THE NOVEL LIQUIDO TECHNIQUE. CONTRARY TO STANDARD SCINTILLATOR TECHNIQUES, IN WHICH THE TRANSPARENCY OF THE SCINTILLATOR IS A REQUIREMENT FOR AN EFFICIENT LIGHT COLLECTION, THE MAJOR BREAKTHROUGH OF LIQUIDO IS THE USE OF AN OPAQUE (IN REALITY, TRANSLUCENT) SCINTILLATOR. ALTHOUGH THIS WORKING PRINCIPLE IS APPARENTLY COUNTERINTUITIVE, THE USE OF AN OPAQUE MEDIUM CAUSES THE STOCHASTIC CONFINEMENT OF THE LIGHT PROVIDING EXCELLENT SPATIAL RESOLUTION AND THEREFORE EVENT TOPOLOGY. IN ADDITION, BY RELAXING THE TRANSPARENCY REQUIREMENTS OF THE SCINTILLATOR, IT OPENS THE POSSIBILITY TO A HIGH CONCENTRATION DOPING IN THE SCINTILLATOR. THEREFORE, THE NEW PROPOSED DETECTOR CONSISTS OF A HEAVILY-DOPED OPAQUE LIQUID SCINTILLATOR WITH HIGHLY GRANULAR READOUT AND 3D TOPOLOGICAL CAPABILITIES. THIS NEW DETECTOR WILL ACT AS A HIGHLY EFFICIENT COSMIC MUON, NEUTRON AND GAMMA TAGGER ALLOWING TO PUSH THE CURRENT BACKGROUND LEVEL OF IAXO AND ITS PREDECESSOR BABYIAXO X-RAY DETECTORS DOWN BY A FACTOR UP TO 100. IN ADDITION, THE NEW DETECTOR WILL BE SENSITIVE TO HIGH ENERGY GAMMAS, EXTENDING THE PHYSICS CASE OF IAXO AS AN AXION SN-SCOPE AS WELL AS 5.5 MEV SOLAR AXION SEARCHES. THE PROPOSED DETECTOR WILL THUS SUBSTANTIALLY BOOST THE SENSITIVITY OF IAXO AND BABYIAXO BY SETTING A NEW STATE-OF-THE-ART IN ULTRA-LOW BACKGROUND TECHNIQUES. AT THE SAME TIME, THIS PROJECT HAS THE CAPABILITIES TO EXPLORE NEW PHYSICS BY THE POTENTIAL DETECTION OF HIGH ENERGY SOLAR AND SN AXIONS. BEYOND AXION PHYSICS THE DEVELOPMENT OF A HEAVILY DOPED RADIOPURE DETECTOR BASED ON THE LIQUIDO TECHNIQUE CAN SET THE BASELINE FOR A NEUTRINOLESS DOUBLE BETA DECAY EXPERIMENT.
