Zvonarev² ¹Joint Institute for Nuclear Research, Dubna, Russia ²Institute of High Energy Physics, Protvino, Russia 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. ª – corresponding author |

Philippov Joint Institute for Nuclear Research, Dubna, Russia Abstract The Nuclotron-based Ion Collider fAcility (NICA) is a new accelerator complex being constructed at JINR aimed to provide collider experiments with heavy ions up to uranium at maximum energy (center of mass) equal to √s ~11 GeV/u. It includes new 6.2 MeV/u linac, 440 MeV/u booster, upgraded SC synchrotron Nuclotron and collider consisting of two SC rings, which provide average luminosity of 1027cm-2∙s-1. The new facility will allow also an effective acceleration of light ions to the Nuclotron maximum energy and an increase of intensity of polarized deuteron beams up to the level above 1010 particles/cycle. Accelerator complex NICA is being built on the experience and technological developments at the Nuclotron facility and incorporates new technological concepts. The scheme of the facility, its operation scenario and beam dynamics are presented in the report. ª – corresponding author |
