Characteristics of the DEGAS-FATIMA Hybrid setup for the DESPEC program at NUSTAR
Résumé
We report on a study of the performance of the DEGAS-FATIMA Hybrid setup through GEANT4 simulations using accurate geometries of all detector components. We give details on the most compact detector configuration considered for this setup when maximising efficiencies of both DEGAS (HpGe) and FATIMA (LaBr 3 (Ce)) systems with respect to a heavy-ion implantation and β-decay station. The possible configurations of the implantation system are discussed in terms of thickness variation and individual positioning of detector components. We provide guidelines for the Hybrid setup for the first NUSTAR/DESPEC experiments.
