Abstract
Spin-orbital dynamics was investigated at COSY accelerator. The key mechanisms of spin-decoherence in the vicinity of the RF spin resonance are covered. The analytical model of spin-decoherence depending on the harmonic number of the RF spin-rotator and the RMS momentum spread was verified. Also the efficiency of spin manipulation with an RF spin-rotator depending on the influence of intrinsic spin resonances and frequency detuning is investigated.
