	The Collector Ring (CR) is a dedicated storage ring in the FAIR project, where the main emphasis is laid on the effective stochastic precooling of intense secondary beams of stable ions, rare isotopes or antiprotons. A complex operation scheme with several types of operational cycles with beams in CR starting from injection, RF gymnastics, stochastic cooling then, and finishing to extraction is foreseen. Beam parameters changes significantly during the cycles. This demands an exceptional high dynamic range for the beam instrumentation. Non-destructive methods are mandatory for high currents as well as for the low current secondary beams due to the low repetition rate. Precise measurements of all beam parameters and automatic steering with short response time are required due to the necessary exploitation of the full ring acceptances. An overview of the challenges and solutions for various diagnostic installations will be given.

	The upgrade of VEPP-2000 e⁺e⁻ collider injection chain includes the connection to BINP Injection Complex (IC) via newly constructed transfer line K-500 as well as upgrade of the booster synchrotron BEP to the energy of 1 GeV. Modernization has started in the middle of 2013 and now the electron and positron beams with highly increased production rate together with top-up injection from BEP are ready to feed VEPP-2000 ring and provide design luminosity at the whole energy range limited only by beam-beam effects. The design and operation experience of IC damping ring, 250 m transfer channel and booster BEP dealing with 2.6 T magnets at top energy will be presented.

	Collector Ring is one of the key installations of the FAIR project (Darmstadt, Germany). It is dedicated for stochastic cooling of incoming beams of antiprotons and rare ions. Additionally there is a mode of operation for experiments in the ring. Beams for all modes of operation are injected through one transfer channel. Extremely high acceptance of the ring (240 mm*mrad) leads to large apertures of all magnetic elements including the septum magnet. Meanwhile planned parameters of the magnetic field and magnetic field quality are comparatively strict. The present state of the design of the pulsed injection septum for the CR is presented in this article together with the concept of the injection system.

The Collector Ring (CR) has been designed for fast cooling of hot antiproton or ion beams at FAIR. Its ion-optical layout and system design has been recently finalized after careful optimizations aiming at improvement of the beam parameters and machine performance. In this paper we present the simulations of the transverse beam dynamics for the different ion-optical modes of the CR. Particle tracking calculations have been performed to evaluate an influence of the magnet imperfections on the dynamic aperture. The analysis and correction of the closed orbit distortions due to the magnet misalignments is also discussed.
