Journal ArticleDOI
Generation of polarized particle beams at relativistic laser intensities
TL;DR: In this paper, the authors present an overview on the current status of the field, on the concepts of polarized laser-plasma accelerators and of the beam polarimetry, as well as an overview of the current state of the research in this field.
Quasi-frozen Spin Method for EDM Deuteron Search
Y. Senichev,Serge Andrianov,Martin Berz,Stanislav Chekmenev,Andrei Ivanov,Andreas Lehrach,Bernd Lorentz,Rudolf Maier,E. Valetov +8 more
TL;DR: In this paper, a quasi-frozen spin was proposed, in which the spin oscillates around the momentum direction within the half value of the advanced spin phase in magnetic arcs, each time returning back in electrostatic arcs.
Journal ArticleDOI
Unexpected enhancements and reductions of rf spin resonance strengths
M. A. Leonova,Vasiliy Morozov,A. D. Krisch,R. S. Raymond,D. W. Sivers,Victor K. Wong,Ralf Gebel,Andreas Lehrach,Bernd Lorentz,R. Maier,D. Prasuhn,A. Schnase,Hans Stockhorst,F. Hinterberger,K. Ulbrich +14 more
TL;DR: In this paper, the authors analyzed all available data on spin-flipping stored beams of polarized protons, electrons, and deuterons and found 10-20fold deviations from the depolarizing resonance strength equations used for many years.
Journal ArticleDOI
Beam dynamics of the high-energy storage ring (hesr) for fair
Andreas Lehrach,K. Bongardt,Bernd Lorentz,R. Maier,D. Prasuhn,Hans Stockhorst,R. Tölle,D. Welsch +7 more
TL;DR: In this article, different beam dynamics issues like closed orbit correction, performance of cooled beams interacting with internal targets and luminosity considerations are discussed in the High-Energy Storage Ring (HESR) of the future International Facility for Antiproton and Ion Research (FAIR).
Journal ArticleDOI
The polarized electron-nucleon collider project ENC at GSI/FAIR
Andreas Lehrach,Kurt Aulenbacher,O Boldt,R Heine,Wolfgang Hillert,Christoph Montag,P Schnizer,T Weis +7 more
TL;DR: In this paper, beam and spin dynamics simulations are presented, together with the required modifications and extensions for a collision mode of the HESR storage ring and the conceptual design of this new collider complex.
