Abstract: Coherent spin motion is a necessary condition to search for the electric dipole moment of charged particles in a storage ring. The first step to increase the spin coherence time is to turn on a radiofrequency cavity. The next step is to manipulate equilibrium energy levels associated with betatron orbit lengthening and nonlinear momentum compaction factor. Spin resonances act as additional sources of decoherence especially for a proton beam.
