Accelerator configuration for polarized proton-antiproton physics at FAIR
TL;DR: The HESR at FAIR as mentioned in this paper accelerates and stores unpolarized antiprotons in the momentum range from 1.5 to 15 Ge V/c. In this paper required modifications and extensions of the accelerator layout are discussed and luminosity estimates presented.

AGS Lattice Changes to Eliminate Weak Intrinsic Resonances
Andreas Lehrach,V. H. Ranjbar +1 more
TL;DR: In this article, the suppression of weak intrinsic spin resonances in the AGS was explored using a family of 12 quadrupoles in the 15 th lattice straight section of each superperiod.
Journal ArticleDOI

Vasiliy Morozov,A. W. Chao,A. D. Krisch,M. A. Leonova,R. S. Raymond,D. W. Sivers,Victor K. Wong,Ralf Gebel,Andreas Lehrach,Bernd Lorentz,R. Maier,D. Prasuhn,Hans Stockhorst,F. Hinterberger,K. Ulbrich,A. Schnase +15 more
TL;DR: In this paper, Chao's proposed matrix formalism for describing the spin dynamics due to a single spin resonance was tested on a deuteron beam stored in COSY, by sweeping an rf dipole's frequency through 200 Hz, while varying the distance from the sweep's end frequency to an Rf induced spin resonance's central frequency.

TL;DR: In this paper, the analyzing powers in proton deuteron elastic and proton-neutron quasi-elastic scattering have been measured at small angles using a polarized proton beam at the COSY storage ring incident on an unpolarized deuterium target.
