Germanium Detector Array

The Germanium Detector Array (or GERDA) experiment is searching for neutrinoless double beta decay (0vββ) in Ge-76 at the underground Laboratori Nazionali del Gran Sasso (LNGS). Neutrinoless beta decay is expected to be a very rare process if it occurs. The collaboration predicts less than one event each year per kilogram of material, appearing as a narrow spike around the 0vββ Q-value (Qββ = 2039 keV) in the observed energy spectrum. This means background shielding is required to detect any rare decays. The LNGS facility has 1400 meters of rock overburden, equivalent to 3000 meters of water shielding, reducing cosmic radiation background.
