The Collector Ring (CR) is a wide aperture storage ring of the FAIR international facility (Darmstadt, Germany) dedicated to perform the stochastic precooling of secondary particles, rare isotopes or antiprotons. BINP (Novosibirsk) takes responsibility on the design and construction of almost all systems of the CR. The project status, preliminary design of main systems and results of the modelling of beam dynamics are presented.

As a result of analysis conducted a transients of the 400 kV column intermediate electrode potential have been determined as one of the main processes responsible for change of beam phase-space portrait orientation during 200 mks, 50 Hz proton injector high voltage accelerating pulse. Beam transport simulation shows high sensitivity of the beam phase-space portrait orientation to variation of the intermediate electrode potential. It has been found that significant variation of this potential takes place due to transition process during a pulse in the capacitor-resistor voltage water divider of the accelerating tube. The divider capacities matching procedure has been performed. The beam emittance measurements results have shown that within the accuracy of observation the beam transverse phase-space portrait orientation remains constant during injector pulse with the accelerating tube voltage divider being compensated.

The overview of electron and positron beams transportation channels from injection complex VEPP-5 to VEPP-4M and VEPP-2000 colliders is presented. The last one is discussed in details. The lattice functions, magnetic elements, beam diagnostic system ans vacuum system are presented. The beam commissioning is scheduled to the end of the year.
