abstract = {Precision experiments, such as the search for electric
dipole moments of charged particles using radio-frequency
spin rotators in storage rings, demand for maintaining the
exact spin resonance condition for several thousand seconds.
Synchrotron oscillations in the stored beam modulate the
spin tune of off-central particles, moving it off the
perfect resonance condition set for central particles on the
reference orbit. Here, we report an analytic description of
how synchrotron oscillations lead to non-exponential
decoherence of the radio-frequency resonance driven
up–down spin rotations. This non-exponential decoherence
is shown to be accompanied by a nontrivial walk of the spin
phase. We also comment on sensitivity of the decoherence
rate to the harmonics of the radio-frequency spin rotator
and a possibility to check predictions of decoherence-free
magic energies.},
