Preliminary Performance Studies of the MoNA-Sweeper setup in S2 at FRIB

The Facility for Rare Isotope Beams (FRIB), which is expected to become operational in 2022, will deliver higher energetic beams (a factor of around two up to 200 MeV) compared to its predecessor, the National Superconducting Cyclotron Laboratory (NSCL). The ability to identify various reaction products from populated reaction channels is therefore essential for any successful scientific program that requires elemental and isotopic separation. Therefore, sufficient resolution must be achieved to identify and differentiate particles with differing proton number (Z) and mass-to- charge ratio (A/q). The LISE++ and nptool (which runs on a ROOT and GEANT4 framework) simulation packages were used to gauge and optimize anticipated capabilities of the Modular Neutron Array and Sweeper Setup within the S2 vault at FRIB. The invariant mass dependence on the resolutions of individual detectors and incoming beam energy will be presented and discussed.
