It was done the studies on high intensity ion beam dynamics in axisymmetric RF linacs both analytically, in terms of the so-called smooth approximation, and numerically in [*,**] rather carefully. For all that, effects of beam self-space-charge field were not taken into consideration under analytical investigations of the focusing by means of non-synchronous harmonics up to date. These effects are said to affect a focusing parameters choice deeply. A “beam-wave” Hamiltonian is derived under assumption that a bunch has an ellipsoidal form. Analytical results specify that given in [**] and it is verified numerically.
