Simulation of the multi-neutron detection at NeuLAND with improved detector response — •Vadim Wagner1, Joachim Enders1, and Dmytro Kresan2 for the R3B collaboration — 1Institut für Kernphysik, TU Darmstadt — 2GSI Helmholtzzentrum für Schwerionenforschung
The future large-area neutron detector NeuLAND for the R3B experiment at FAIR is bound to detect neutrons from reactions of exotic nuclei. Among the challenges are the detection of low-energy neutrons with good resolution as well as the simultaneous detection of up to four neutrons.
This contribution presents simulation results with an improved representation of the detector response for NeuLAND in the R3BRoot framework. From the present results, an energy resolution for a single neutron of 13 keV can be expected. A two-dimensional reconstruction of the neutron multiplicity allows 4n events to be reconstructed with an efficiency of about 56%, an increase of about 60% with respect to previous simulations.
Supported in part by the state of Hesse through the LOEWE center HIC for FAIR.
