Abstract: | One of the basic facilities at the Joint Institute for Nuclear Research (JINR) in Dubna is the 6 A GeV Nuclotron, which has replaced the old weak focusing 10-GeV proton accelerator Synchrophasotron. The first relativistic
nuclear beams with the energy of 4.2 A GeV were obtained at the Synchrophasotron in 1971. Since that time, relativistic nuclear physics has been one of the main
directions of the JINR research program. In the coming years, the new JINR flagship program assumes the experimental study
of hot and dense strongly interacting QCD matter at the new JINR facility. This goal is proposed to be reached by (i) development
of the existing Nuclotron accelerator facility as a basis for generation of intense beams over atomic mass range from protons
to uranium and light polarized ions, (ii) design and construction of the Nuclotron-based heavy Ion Collider fAcility (NICA)
with the maximum nucleon-nucleon center-of-mass collision energy of √s
NN
= 9 GeV and averaged luminosity 1027 cm−2 s−1, and (iii) design and construction of the Multipurpose Particle Detector (MPD) at intersecting beams. Realization of the
project will lead to unique conditions for research activity of the world community. The NICA energy region is of major interest
because the highest nuclear (baryonic) density under laboratory conditions can be reached there. Generation of intense polarized
light nuclear beams aimed at investigation of polarization phenomena at the Nuclotron is foreseen.
