Decoherence of a longitudinally kicked beam with chromaticity
In this report a method to measure the chromaticity is presented. This method consists in applying a longitudinal kick and computing the Fourier transform of the transverse turn-by-turn BPM readings.

| Sumario: | In this report a method to measure the chromaticity is presented. This method consists in applying a longitudinal kick and computing the Fourier transform of the transverse turn-by-turn BPM readings. An analytical expression for the Fourier transform is derived, which shows how the chromaticity can be inferred from the synchrotron sidebands. Finally, a multiparticle simulation is performed to validate the analytical expression. |
