Abstract

General goal of the NICA/MPD project under realization at JINR is to start in the coming 5÷7 years an experimental study of hot and dense strongly interacting QCD matter and search for possible manifestation of signs of the mixed phase and critical endpoint in heavy ion collisions. The Nuclotron-based Ion Collider fAcility (NICA) and the Multi Purpose Detector (MPD) are proposed for these purposes. The NICA collider is aimed to provide experiment with heavy ions like Au, Pb or U at energy up to 3.5×3.5 GeV/u with average luminosity of 10²⁷ cm^-2∙s^-1 and to provide collisions of light ions in the total energy range available with the Nuclotron. New injector designed for efficient operation of the NICA facility is based on Electron String Ion Source providing short (< 10 μs) and intensive pulses of U³²⁺ ions, one section of RFQ and four sections of RFQ Drift Tube Linac accelerating the ions at Z/A 0.12 up to 6.2 MeV/u of the kinetic energy. General parameters of the injector are discussed.
