Correctors’ Magnets for the NICA Booster and Collider

The NICA accelerator complex will consist of two injector chains, a new 600 MeV/u superconducting booster synchrotron, the existing superconducting synchrotron—Nuclotron, and the new superconducting collider that has two storage rings each of about 503 m in circumference. The influence of the fringe fields and misalignments of the structure magnets, the field imperfections and natural chromaticity should be corrected by the correction system. The main parameters, arrangements and the field calculations of the corrector magnets are presented.
