Abstract

The Gerda experiment, located at the Laboratori Nazionali del Gran Sasso (LNGS) of INFN in Italy, searches for the neutrinoless double beta (0νββ) decay of ⁷⁶Ge. Gerda Phase II is aiming to reach a sensitivity for the 0νββ half life of 10²⁶ yr in ∼ 3 years of physics data taking with 100 kg•yr of exposure and a background index of ∼ 10^-3 cts/(keV•kg•yr). After 6 months of acquisition a first data release with 10.8 kg•yr of exposure is performed, showing that the design background is achieved. In this work a study of the Phase II background spectrum, the main spectral structures and the background sources will be presented and discussed.
