Transverse beam echo measurements on a single proton bunch at the SPS

This MD was aimed at proving the possibility of detecting beam echo signals in the transverse plane by using two dipole kicks. We have confirmed that when a proton bunch suffers a transverse dipole kick and the betatron oscillations of the centroid are damped due to the decoherence induced by nonlinearities, a subsequent dipole kick restores, after a delay, those betatron oscillations in the form of an echo signal.
