  The frequency analysis of the betatron motion is a valuable tool for the characterization of the linear and non-linear motion of a particle beam in a storage ring. In recent years, several experiments have shown that resonance driving terms can be successfully measured from the spectral decomposition of the turn-by-turn BPM data. The information on the driving terms can be used to correct unwanted resonances, to localize strong non-linear perturbations and provides a valuable tool for the construction of the non-linear model of the real accelerator. In this paper we introduce briefly the theory, the computational tools and we give a review of the resonance driving terms experiments performed on different circular machines.

The transverse echo amplitudes observed in RHIC will be analysed using particle tracking codes together with different kinetic intrabeam scattering models. We discuss the different diffusion rates observed in proton and heavy ion beams.
