Introduction: Development of the NICA Concept and TDR
Since publication of the 1-st version of the NICA CDR
The Concept was developed and the volumes I and II
of the TDR have been completed:
Volume I – Part 1, General description
Part 2, Injector complex
Volume II – Part 3, Booster-Synchrotron
A brief review of the Project, its status and plans of
realization are presented here.

Round Table Workshop IV I.Meshkov, Status of the NICA TDR JINR, Dubna September 1, 2009
Introduction: Development of the NICA Concept and TDR
The Project goals formulated in NICA CDR
are the following:
1a) Heavy ion colliding beams 197Au79+ x 197Au79+ at
sNN = 4 11 GeV (1 4.5 GeV/u ion kinetic energy )
at
Laverage= 11027 cm-2s-1 (at sNN = 9 GeV);
1b) Light-Heavy ion colliding beams of the energy range and luminosity
(“the reference” collider mode);
2) Polarized beams of protons and deuterons:
pp sNN = 12 25 GeV (5 12.6 GeV kinetic energy ),
dd sNN = 4 13.8 GeV (2 5.9 GeV/u ion kinetic energy ).

Two injection schemes are considered:
1) bunch by bunch injection, 17 bunches: bunch number is limited by kicker pulse duration bunch compression in Nuclotron is required (!) Electron and/or stochastic cooling is used
for luminosity preservation
2.2. Collider (Contnd)
!
2) Injection and storage with barrier bucket
technique and cooling of a coasting (!) beam, 20
bunches, bunch number is limited by interbunch space in IP straight
section bunch compression in Nuclotron is NOT required (!) Electron and/or stochastic cooling for storage and
luminosity preservation, bunch formation after storage are
required.
