NEULAND at R3B: Multi-Neutron Response and Resolution of the Novel Neutron Detector — •Dmytro Kresan1, Thomas Aumann1, Konstanze Boretzky2, Denis Bertini2, Michael Heil2, Dominic Rossi2, and Haik Simon2 — 1Technische Universität Darmstadt, Darmstadt, Germany — 2GSI Helmholzzentrum für Schwerionenforschung, Darmstadt, Germany
NEULAND (New Large Area Neutron Detector) will serve for the detection of fast neutrons (200 - 1000 MeV) in the R3B experiment at the future FAIR. A high detection efficiency (>90%), a high resolution (down to 20 keV) and a large multi-neutron-hit resolving power (≥5 neutrons) are demanded. The detector concept forsees a fully active and highly granular design of plastic scintillators. We present the detector capabilities, based on simulations performed within the FairRoot framework. The relevance of calorimetric properties for the multi-hit recognition is discussed, and examplarily the performance for specific physics cases will be presented.
