This thesis contains the installation of a low energy “SiriusSD R© Silicon Drift Detector” as well as a background study and a first investigation on three samples, namely 151Sm, 193Pt and 158Tb, which were recently activated with a neutron field at the DT generator of the IKTP at Helmholtz-Zentrum Dresden-Rossendorf. The experiment is built within the shallow-underground “Felsenkeller” laboratory, with 45 meter of rock overburden which massively reduces the rate of cosmic background radiation and is therefore used for low background setups. The measurements contain first test experiments to verify the settings followed by background measurements with two different detector orientations. Inspired by that the next experiment investigated the amount of muon induced signals in the detector. The next part was a first energy calibration and efficiency calibration, especially the energy calibration was necessary for the last experiments, namely the investigation of the new samples. These contain first spectra of the recently activated samples, which shall give a basic framework for further improvements and measurements done with these samples. The last part of this thesis contains a summary of the results, a discussion on how the experiments shall be improved and an outlook is given on the improvements and experiments that are important for the detector and the new samples.
