Thorium-229 in its Highest Charge States: Single-Ion Nuclear Clocks for Tests of Fundamental Interactions
C. Brandau, P. Micke, I. Hartl +6
The prospects and the implementation of single-ion nuclear clocks of Th ions in their highest charge states are discussed. Highly-ionized-thorium…
A Digital Feedback System for Advanced Ion Manipulation Techniques in Penning Traps
Jost Herkenhoff, Menno Door, Pavel Filianin +7
The possibility to apply active feedback to a single ion in a Penning trap using a fully digital system is demonstrated. Previously realized feedback systems rely on analog circuit…
The Heidelberg compact electron beam ion traps
P. Micke, S. Kühn, L. Buchauer +16
Electron beam ion traps (EBIT) are ideal tools for both production and study of highly charged ions (HCI). In order to reduce their construction, maintenance, and operation costs w…
Detection of metastable electronic states by Penning trap mass spectrometry
Rima Xenia Schüssler, Hendrik Bekker, Martin Braß +19
State-of-the-art optical clocks achieve fractional precisions of and below using ensembles of atoms in optical lattices or individual ions in radio-frequency traps. Prom…
Production of highly charged ions of rare species by laser-induced desorption inside an electron beam ion trap
Christoph Schweiger, Charlotte König, José R. Crespo López-Urrutia +13
This paper reports on the development and testing of a novel, highly efficient technique for the injection of very rare species into electron beam ion traps (EBITs) for the product…
