	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.

	O.A. Kovalenko, A. Dolinskyy, O.E. Gorda, S.A. Litvinov GSI, Darmstadt, Germany
	The Orbit Response Matrix (ORM) analysis is a method which allows to find the sources of discrepancies between design and real optics of an accelerator machine. In particular, with this technique one retrieves information about gradient errors, dipole corrector gain errors etc. Orbit response matrix is computed by measuring orbit deviations caused by single kicks of corrector magnets. With fitting the matrix one obtains the ion optics which best describes the real accelerator. The ORM analysis, presented in the paper, is employed to find error sources in the FAIR storage rings CR and HESR during and after the beam commissioning. The algorithm itself was implemented in Python programming language with a help of linear algebra libraries. The ORM analysis accuracy as well as its limitations are addressed in the paper.

	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).
