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 (76)Ge. Gerda Phase II is aiming to reach a sensitivity for the 0νββ half life of 10(26) 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.
