An electric dipole moment (EDM) in the neutron would indicate a source of CP-violation that is needed to explain the dominance of matter over antimatter in the universe. Several experiments are currently looking for a neutron EDM and so far, the value has been constrained to dn 1.8 x10 26 ecm. Presented here is work supporting the nEDM experiment at Los Alamos National Laboratory which utilizes ultracold neutrons (UCNs) and Ramsey’s separated oscillating fields method. In such an experiment, it is important to understand the velocity of the neutrons due to false EDM signals that can be pro- duced by the presence of a magnetic field. Monte Carlo simulations were used to study the optimal design parameters of a chopper system that would reproduce a given velocity spectrum of a population of neutrons by measuring the time of flight to a detector.
