Characterization of Germanium crystals using PET — •Lukas Rauscher, Büsra Cebeci, and Josef Jochum for the GERDA collaboration — Physikalisches Institut, Auf der Morgenstelle 14, Tübingen, Deutschland

To increase their sensitivity several neutrino experiments want to significantly reduce background contributions by active background-suppression techniques. One of these techniques is the pulse shape analysis of signals induced by the interaction of radiation with the detector. The pulse shapes do not only depend on the energy of the interacting particle, the geometry and the field configuration but also on the location of interaction within the crystal. One possibility to determine the waveform depending on the location of the interaction in the detector is the use of positron-emission-tomography (PET). The main goal of this work is to create a setup which can characterize a detector using a PET. The poster shows a proof of principle and also the ongoing work on the subject. This work is funded by the BMBF.
