Description
The global scientific goal of the NICA/MPD (Nuclotron-based Ion Collider
fAcility / Multy Purpose Detector) project under realization at JINR is to
explore the phase diagram of strongly interacting baryonic matter in the
region of a high compression and temperature. The proposed program allows
one to search for possible signs of the phase transitions and critical
phenomena in heavy ion (up to Au+Au) collisions up to to energies of 11
GeV in nucleon- nucleon center-of-mass system.The collider experiment
provides optimal conditions for efficient energy scan measurements.
However, the accelerator task to reach required average luminosity of the
order of 10^27 cm^-2*s^-1 is challenging: in contrast with a high
energy collider the luminosity is limited by Lasslet tune shift, the
beam-beam parameter is almost negligible. A flexible procedure of the beam
storage and short bunch formation is to be applied to provide maximum peak
luminosity in a wide energy range. The application of beam cooling methods
is mandatory in order to suppress luminosity dilution due to the
intra-beam scattering. A solution of these and other problems is
demonstrated in the case of the NICA collider design.
