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…
Penning-trap measurement of the -value of the electron capture in for the determination of the electron neutrino mass
Christoph Schweiger, Martin Braß, Vincent Debierre +19
The investigation of the absolute scale of the effective neutrino mass remains challenging due to the exclusively weak interaction of neutrinos with all known particles in the stan…
Mass-difference measurements on heavy nuclides with at an eV/c2 accuracy level with PENTATRAP
A. Rischka, H. Cakir, M. Door +13
First ever measurements of the ratios of free cyclotron frequencies of heavy highly charged ions with Z>50 with relative uncertainties close to 1e-11 are presented. Such accurate m…
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…
P. Filianin, C. Lyu, M. Door +15
The cyclotron frequency ratio of to ions was measured with the Penning-trap mass spectrometer PENTATRAP. The achieved result of…
Trapped Ion Quantum Computing using Optical Tweezers and Electric Fields
M. Mazzanti, R. X. Schüssler, J. D. Arias Espinoza +3
We propose a new scalable architecture for trapped ion quantum computing that combines optical tweezers delivering qubit state-dependent local potentials with oscillating electric…
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…
Direct Measurement of the Mass Difference of Ho163 and Dy163 Solves the Q-Value Puzzle for the Neutrino Mass Determination
S. Eliseev, K. Blaum, M. Block +14
The atomic mass difference of 163Ho and 163Dy has been directly measured with the Penning trap mass spectrometer SHIPTRAP applying the novel phase imaging ion cyclotron resonance t…
