Abstract
The NICA (Nuclotron-based Ion Collider fAcility) project is now under active realization at the Joint Institute for Nuclear Research (JINR, Dubna). The main goal of the project is a study of hot and dense strongly interacting matter in heavy ion (up to Au) collisions at the centre-of-mass energies up to 11 GeV per nucleon. Two modes of operation are foreseen, collider mode and extracted beams, with two detectors: MPD and BM@N. The both experiments are in preparation stage. An average luminosity in the collider mode is expected as 10E27 cm-2 s-1 for Au (79+). Extracted beams of various nucleus species with maximum momenta of 13 GeV/c (for protons) will be available. A study of spin physics with extracted and colliding beams of polarized deuterons and protons at the energies up to 27 GeV (for protons) is foreseen with the NICA facility. The proposed program allows one to search for possible signs of phase transitions and critical phenomena as well as to shed light on the problem of the nucleon spin structure.
Highlights
The Nuclotron at Veksler and Baldin Laboratory of High Energy Physics (VBLHEP) of JINR was put into operation in 1993
The NICA facility (Fig. 2) includes: the injection complex, the booster, the upgraded Nuclotron and two storage rings with two interaction points IP1 and IP2 aimed at the MPD and SPD detectors respectively
The injection complex provides a wide set of ion species up to the heaviest one, Au, at an energy of 3.5 MeV/u with an expected intensity of 2·10E9 particles per cycle.The main efforts at the present time are devoted to completion of beam tests of both heavy ion, KRION-6T, and polarized proton and deuteron, source of polarized ions (SPI), sources aimed at reaching of the specified parameters and to completion of manufacturing of the HILAC and the new RFQ fore-injector that should replace the old high voltage pulsed transformer at the linac LU-20
