Abstract
The transient beam response to an external impulse force in synchrotrons with a digital transverse feedback system is studied. The experimental data on damping coherent transverse oscillations of bunch excited by a discrete-time unit impulse in the Large Hadron Collider (LHC) are analyzed. Good agreement between the measured and theoretically predicted decrements has been obtained. A method of feedback fine tuning based on measurements of the bunch response to a harmonic excitation impulse is discussed.
