Probing neutrino interactions with smaller, more sensitive detectors
Detecting neutrinos typically requires heavy, large-sized detectors. A recently observed particular interaction of neutrinos with atomic nuclei, called the coherent elastic neutrino-nucleus scattering, could be used to probe neutrinos with smaller-scale experiments. However, observing this interaction requires a source of low-energy neutrinos, and the European Spallation Source in Lund (Sweden) has been identified as optimal in this regard. The EU-funded GanESS project aims to develop a time projection chamber (a particle detector for reconstructing particle trajectories or interactions) that can hold 20 kg of xenon gas at a high pressure. The proposed detector that will be installed in the European Spallation Source is expected to be more sensitive to coherent elastic neutrino-nucleus scattering events.
