	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.

	In the framework of antiproton program at FAIR project, the large acceptance antiproton separator is dedicated for the effective separation of the secondary antiprotons from the primary protons and the secondary beams of other particle species and subsequent transportation to the Collector Ring (CR). Here we present the latest ion-optical layout of the antiproton separator and possible second-order correction scheme as well.

	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.

	A design of beam optics will be presented for the FCC-ee double-ring collider. The main characteristics are 45 to 175 GeV beam energy, 100 km circumference with two IPs/ring, 30 mrad crossing angle at the IP, crab-waist scheme with local chromaticity correction system, and "tapering" of the magnets along with the local beam energy. An asymmetric layout near the interaction region suppresses the critical energy of synchrotron radiation toward the detector at the IP less than 100 keV, while keeping the geometry as close as to the FCC-hh beam line. A sufficient transverse/longitudinal dynamic aperture is obtained to assure the lifetime with beamstrahlung and top-up injection. The synchrotron radiation in all magnets, the IP solenoid and its compensation, nonlinearity of the final quadrupoles are taken into account.
