	Since last RuPAC two runs of the Nuclotron operation were performed. The run #54 performed in February ' March of 2017 was dedicated to polarized beam acceleration. One of the achievements was the acceleration of polarized proton beam performed at the Nuclotron for the first time. During the run #55 in February- April of 2018 the Nuclotron provided heavy ion beams for first fixed target experiments in the frame of the NICA scientific program. These and other results of the facility operation and development are presented.

	Modern accelerators are made with high-field superconducting dipoles, quadrupoles and sextupoles that exhibit unintentional imperfections of the guiding field-shape due to construction tolerances, persistent currents and magnetic saturation. This deviation from linearity has a profound influence on the beam dynamics. In this work the research of nonlinear beam dynamics for the NICA booster was carried out. Sextupole and octupole fields for dipole and quadrupole magnets, according to ongoing magnetic measurements, were taken into account, as well as adjustment errors for magnets. Numerical simulation in MADX program has been used to evaluate the dynamic aperture for the booster. In addition, betatron tune shift with amplitude was calculated. The results showed that dynamic aperture is exceeded its geometrical acceptance at least in three times.
