Status of the Development of Superconducting Magnets for the NICA Project

NICA is a new accelerator complex that is being under design and construction at JINR. The facility is aimed at providing collider experiments with heavy ions up to Uranium in a center of mass energy range from 4 to 11 GeV/u and an average luminosity up to 10²⁷ cm^-2 s^-1. The collisions of polarized deuterons are also foreseen. The facility includes two injector chains, a new superconducting booster synchrotron, the existing 6 superconducting synchrotron-Nuclotron, and a new superconducting collider consisting of two rings, each of about 503 m in circumference. The booster synchrotron and the NICA collider are based on an iron-dominated “window frame”-type magnets with a hollow superconductor winding analogous to the Nuclotron magnet. The status of the development of the full size model magnets for the booster synchrotron as well as for the NICA collider is presented.
