The Nuclotron accelerator is a strong-focusing synchrotron designed to provide beams of multicharged ions with energies of up to 6 GeV / nucleon, protons and polarised deuterons. The Nuclotron has been based on the unique technology of superconducting magnets proposed and developed in the Laboratory of High Energy Physics. Design and engineering development, testing and assembly of the Nuclotron elements have been performed by the efforts of the Laboratory staff-members.
