A slowly varying horizontal electrostatic field may be useful to de-excite synchrotron oscillations. Then we have to somehow observe the damping of amplitudes of synchrotron oscillations to confirm the effect. We assume that the synchrotron component of rationalized Hamiltonian in acceleration stage is kept constant. Our experimental results did not contradict with this assumption. Taking advantage of this assumption, we can easily confirm the damping of synchrotron oscillation amplitudes experimentally through the increase of synchrotron frequencies.
