Abstract / Description:Observation of neutrinoless double beta decay could answer the question regarding the Majorana or Dirac nature of
neutrinos. The Gerda experiment utilizes HPGe detectors enriched with the isotope 76Ge to search for this process.
Recently the Gerda collaboration has unblinded data of Phase I of the experiment. In order to further improve the
sensitivity of the experiment, additionally to the coaxial detectors used, 30 BEGe detectors made from germanium
enriched in 76Ge will be deployed in Gerda Phase II.
BEGe detectors have superior PSD capability, thus the background can be further reduced. The liquid argon surrounding
the detector array will be instrumented in order to reject background by detecting scintillation light induced
in the liquid argon by radiation. After a short introduction the hardware preparations for Gerda Phase II as well as the
processing and characterization of the 30 BEGe detectors are discussed.
