Description
The detection of dark matter remains a central challenge in particle physics. Liquid argon (LAr) based experiments, like DEAP-3600, must understand potential background signals mimicking dark matter in order to achieve maximum sensitivity. Argon-1, a modular LAr detector at Carleton University utilizing silicon photomultipliers, provides a platform to study key background sources, aiding not only DEAP-3600 but also future detectors like the 400-tonne ARGO detector and its prototype, ARGOlite.
This talk presents measurements by Argon-1 of alpha scintillation quenching, a process through which a fraction of the energy deposited is not converted to scintillation light, with quenching factors depending, in general, on energy. These results complement the DEAP-3600 collaboration’s 2024 publication, extending quenching factor measurements into energy ranges inaccessible to DEAP-3600 due to contamination risks. Additionally, Argon-1’s contributions to benchmarking simulations for ARGO and ARGOlite are discussed, in preparation for the next generation of argon-based dark matter detectors.
