Dynamic Aperture of the NICA Collider Optimized with a Genetic Algorithm

NICA (Nuclotron-based Ion Collider fAcility) [1] is a heavy-ion collider for studying the properties of hot and dense baryonic matter to be constructed at JINR (Dubna). A major restricting factor on the NICA’s transverse dynamic aperture is the nonlinear fringe field of final-focus quadrupole lenses. We propose to enhance the NICA dynamic aperture with a set of multipole lenses whose characteristics and configuration are optimized using a genetic algorithm.
