Borexino gathers the first directional measurement of sub-MeV solar neutrinos using a monolithic scintillation detector

Borexino is a large-scale particle physics experiment that collected data until October 2021. Its key mission was to study low energy (sub-MeV) solar neutrinos using the Borexino detector, the world's most radio-pure liquid scintillator calorimeter, located at the Laboratori Nazionali del Gran Sasso near Aquila, in Italy.
