Simulations for a Multi-Reflection Time-of-Flight Mass Spectrometer at the University of Notre Dame

A multi-reflection time-of-flight mass spectrometer (MR-ToF) has been built at the University of Notre Dame. The MR-ToF will provide isobarically pure ion bunches to experiments at Argonne National Laboratory's (ANL) future ``N $=$ 126 Factory'', a unique facility capable of producing very neutron-rich nuclei around the N $=$ 126 shell closure. Prior to its installation at ANL, the MR-ToF is being evaluated in an off-line test setup consisting of a surface ion source, a Bradbury-Nielsen Gate (BNG) to chop the beam before injection into the MR-ToF, and a micro-channel plate detector to record the resulting bunches. The series of~simulations investigating the feasibility of this bunching method, as well as the injection of these bunches into the MR-ToF, will be presented.
