Description
One important aspect of the study of systematic effects in room-temperature (RT) nEDM is the center of mass offset of the stored ultracold neutrons (UCN) due to gravity and the Larmor frequency shift connected to it.
We will present simulation results on such a shift and on the transversal depolarization time (T2) of the UCN (affecting sensitivity) as a function of realistic magnetic fields which were parametrized from offline mapping measurements.
We show that the fraction of diffuse reflections and the energy spectrum of the UCN play a major role, and will also compare to theoretical predictions for simple magnetic field configurations serving as bench-marks for the realistic field calculations.
