Abstract :
Theory predicts that resonance driving terms can be determined by harmonic analysis of BPM data recorded after applying single kicks. In recent experiments at the CERN SPS this technique has been successfully applied to measure coupling and sextupolar resonance terms around the ring. A similar experiment has been carried out in RHIC, BNL, to prove the feasibility of this measurement in this more complex machine. Promising results of the experiment are presented, including a direct measurement of sextupolar resonances and a comparison to the model.
