Journal ArticleDOI
Electronic g Factor of Hydrogenlike Oxygen O-7 + 16
J. Verdú,S. Djekic,S. Stahl,T. Valenzuela,Manuel Vogel,Günter Werth,Thomas Beier,H.-J. Kluge,Wolfgang Quint +8 more
TL;DR: An experimental value for the g factor of the electron bound in hydrogenlike oxygen is found to be g(expt)=2.000 047 025 4 (15)(44), which represents a stringent test of bound-state quantum electrodynamics to a 0.25% level.
Journal ArticleDOI
Double Penning trap technique for precise g factor determinations in highly charged ions
Hartmut Häffner,Thomas Beier,S. Djekic,N. Hermanspahn,H.-J. Kluge,Wolfgang Quint,S. Stahl,J. Verdú,T. Valenzuela,G. Werth +9 more
TL;DR: In this article, a detailed description of an experiment to determine the magnetic moment of an electron bound in hydrogen-like carbon is presented, which forms a high-accuracy test of bound-state quantum electrodynamics.
Journal ArticleDOI
A planar Penning trap
S. Stahl,Fernando Galve,J. Alonso,S. Djekic,Wolfgang Quint,T. Valenzuela,J. Verdú,Manuel Vogel,G. Werth +8 more
TL;DR: In this paper, a planar Penning trap is proposed, which provides confinement perpendicular to its plane by an electric potential minimum while a superimposed magnetic field provides radial confinement, and switches between different traps in the planar array allow for controlled interactions between the single stored particles.
Journal ArticleDOI
Phase-sensitive measurement of trapped particle motions
TL;DR: In this paper, a method for the precise determination of small frequency differences of particle motions inside a Penning trap was developed and applied to determine the spin state of an electron bound in a hydrogen-like ion.
Book ChapterDOI
HITRAP: A Facility for Experiments with Trapped Highly Charged Ions
Wolfgang Quint,Jens Dilling,S. Djekic,Hartmut Häffner,N. Hermanspahn,H.-J. Kluge,Gerrit Marx,R. B. Moore,Daniel Rodríguez,J. Schönfelder,G. Sikler,T. Valenzuela,J. Verdú,Christian Weber,G. Werth +14 more
TL;DR: HITRAP as discussed by the authors is a planned ion trap facility for capturing and cooling of highly charged ions produced at GSI in the heavy-ion complex of the UNILAC-SIS accelerators and the ESR storage ring.
