Test of Time Dilation Using Stored Li + Ions as Clocks at Relativistic Speed
B. Botermann,Dennis Bing,Christopher Geppert,Gerald Gwinner,Theodor W. Hänsch,G. Huber,Sergei Karpuk,A. Krieger,T. Kuhl,Wilfried Nörtershäuser,Wilfried Nörtershäuser,C. Novotny,S. Reinhardt,Rodolfo Sánchez,Dirk Schwalm,Thomas Stöhlker,Andreas Wolf,Guido Saathoff +17 more
TL;DR: The concluding result from an Ives-Stilwell-type time dilation experiment using 7Li+ ions confined at a velocity of β=v/c=0.338 in the storage ring ESR at Darmstadt is verified and interpreted within Lorentz invariance violating test theories.
Journal ArticleDOI

TL;DR: In this article, an optical technique to study the longitudinal distribution of ions in a bunched ion beam circulating in a storage ring is presented based on the arrival-time analysis of photons emitted after collisional excitation of residual gas molecules.
