New results with unsegmented p-type BEGe detectors for GERDA Phase II — Matteo Agostini, Marik Barnabé Heider, •Dušan Budjáš, and Stefan Schönert — Max-Planck-Institut für Kernphysik, Heidelberg, Germany
The GERDA experiment employs isotopically enriched Ge detectors to search for neutrinoless double beta decay of 76Ge. One experimental technique necessary for reducing background in GERDA is the analysis of detector signal time-structure. Enhanced event discrimination power was demonstrated with an unsegmented p-type detector (BEGe), which is one of prototype detector candidates for GERDA Phase II. Results from recent studies of the signal generating process and from operational tests of bare prototype submerged in LAr will be presented.
