	Charge particle beams transportation with small cross-sections and low energies is an actual problem for a gantry. That beams are used actively for isotope therapy. Beam emittance is its quality factor, and it should be matched with a facility channel acceptance. The method for beam dynamics analysis in lattice is developed in terms of non-coherent particle oscillation study. Nonlinear beam dynamics is investigated by using this method. It is shown that this technique allows one to realize effective beam emittance control. Analytical results obtained are verified by means of numerical simulation.

	The problem of the effective low-energy linac design is of interest to many fields of science, industry and medicine. It is well known that nonsynchronous harmonics of RF field (RF undulator) are focusing the particles.

Motion equation is presented in the form of the Hamilton's equations. Motion integrals are found by means of Poincare mapping.
