Despite the difficulties caused by the pandemic, the implementation of the NICA complex is successfully moving forward. It will have the form of a multi-stage cascade of accelerators. Before entering the main ring of the collider, ions will be previously accelerated in other units of the facility. Superconducting magnets are used to accelerate particles and keep them on the required path. The technology of magnets was developed at the Joint Institute. The success of the facility and beam parameters directly depends on the quality of the magnets. Assistant Director for the Implementation of Infrastructure Projects of the Veksler and Baldin Laboratory of High Energy Physics Sergey Kostromin comments how such magnets used for ring accelerators including at the NICA complex are designed, describes their characteristics and the production process in a series of videos.

It should be reminded that scientists successfully transported a beam of iron ions from the Booster of the NICA complex through the Booster-Nuclotron channel for the first time in September of this year.
