  NICA is a proton and heavy ion collider being built at JINR in Dubna, Russia. It was shown that nonlinear quadrupole fringe fields are among the main factors limiting dynamic aperture of the machine. In the present paper the following ways of dynamic aperture optimization were studied: betatron tunes optimization and placing octupole lenses to the lattice to compensate fringe fields' effect.

  Symmetry properties of 6D and 4D one-turn symplectic transport matrices were studied. A new parameterization was proposed for 6D matrix, which is an extension of the Lebedev-Bogacz parameterization for 4D case. The parameterization is fully symmetric relative to radial, vertical and longitudinal motion. It can be useful for lattices with strong coupling between all degrees of freedom.
