Performance test of the GERDA Phase II detector assembly — •Tobias Bode1, Konstantin Gusev1, Bernhard Schwingenheuer2, and Victoria Wagner2 for the GERDA collaboration — 1Technische Universität München, München — 2Max-Planck Institut für Kernphysik, Heidelberg
After the successful completion of Phase I the GERDA (Germanium Detector Array) experiment will continue the search for the neutrinoless double beta decay (0νββ) of 76Ge with the improved setup of Phase II. To achieve a half-life sensitivity of 1026 yr the target mass will be doubled and a reduction of background index to <10−3 cts/(keV kg yr) is aimed for. Major hardware modifications and upgrades are currently on going. They include the deployment of a new radio pure low mass detector assembly and use of radio pure close-by preamplifying electronics. The performance of the Phase II detector assembly will be presented. This work was partly funded by BMBF 05A11W01.
