Description

Resonant depolarization measurements offer a promising method for the high
precision center-of-mass energy calibration that can be applied in the FCC-ee.
Simulations need to be performed to validate the obtainable polarization limits
under the influence of perturbed orbits. This study offers the first exploration
of the FCC-ee spin polarization simulations using Bmad. The relations between
the linear polarization limits and the energies under different conditions have
been investigated. The results of benchmarks with SITROS as well as the results
of nonlinear spin tracking using the Long Term Tracking module in Bmad are
presented.
