Abstract

The new Oslo Scintillator Array (OSCAR) has been commissioned at the Oslo Cyclotron Laboratory (OCL). It consists of 30 large volume (diameter 3.5 x 8 inches) LaBr $_3$ (Ce) detectors that are used for $\gamma$ -ray spectroscopy. The response functions for incident $\gamma$ -rays up to 20 MeV are simulated with $\texttt{Geant4}$ . In addition, the resolution, and the total and full-energy peak efficiencies are extracted. The results are in very good agreement with measurements from calibration sources and experimentally obtained mono-energetic in-beam $\gamma$ -ray spectra.
