Characterisation of the new HPGe detectors at INPP/NCSR “Demokritos”... and future (n,2n) reactions to be studied

Within the present work HPGe detectors of Institute Nuclear and Particle Physics at NCSR “Demokritos” were fully characterized in terms their efficiency. The three n-type 80% relative efficiency recently acquired framework CALIBRA project. All are equipped with carbon epoxy windows that allow detection low energy γ-rays. Beside characterization, modeled by means GEANT4. In all cases simulated detector geometries fine-tuned so as to reproduce experimental data different source-to-detector distances. Finally, a demonstration new offered abilities, characterization GEANT4 modeling was used for feasibility study possible/future (n,2n) activation measurements on medium-weight nuclei.
