Stringent test of QED with hydrogenlike tin
J. Morgner, B. Tu, C. M. König +11
Inner-shell electrons naturally sense the electric field close to the nucleus, which can reach extreme values beyond for the innermost electrons. Espe…
Perspectives on testing fundamental physics with highly charged ions in Penning traps
Klaus Blaum, Sergey Eliseev, Sven Sturm
In Penning traps electromagnetic forces are used to confine charged particles under well-controlled conditions for virtually unlimited time. Sensitive detection methods have been d…
Penning-trap mass measurements of the deuteron and the HD+ molecular ion
Sascha Rau, Fabian Heiße, Florian Köhler-Langes +7
The masses of the lightest atomic nuclei and the electron mass are interlinked and are crucial in a wide range of research fields, with their values affecting observables in atomic…
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…
Tank-Circuit Assisted Coupling Method for Sympathetic Laser Cooling
Bingsheng Tu, Felix Hahne, Ioanna Arapoglou +9
We discuss the coupling of the motion of two ion species in separate Penning traps via a common tank circuit. The enhancement of the coupling assisted by the tank circuit is demons…
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…
High-precision mass spectrometer for light ions
Fabian Heiße, Sascha Rau, Florian Köhler-Langes +4
The precise knowledge of the atomic masses of light atomic nuclei, e.g. the proton, deuteron, triton and helion, is of great importance for several fundamental tests in physics. Ho…
-factor of Boronlike Argon
I. Arapoglou, A. Egl, M. Höcker +15
We have measured the ground-state -factor of boronlike argon with a fractional uncertainty of \SI{1.4e-9}{} with a single ion in the newly developed ALP…
Factor of Lithiumlike Silicon: New Challenge to Bound-State QED
D. A. Glazov, F. Köhler-Langes, A. V. Volotka +7
The recently established agreement between experiment and theory for the factors of lithiumlike silicon and calcium ions manifests the most stringent test of the many-electron…
The Basic and the Charge Density Wave Modulated Structures of NbS3-II
E. Zupanič, H. J. P. van Midden, M. van Midden +10
The basic and the charge density wave (CDW) structures of the monoclinic polymorph were studied by synchrotron x-ray diffraction, ab-initio calculation, simulation of el…
High-precision measurement of the atomic mass of the electron
Sven Sturm, Florian Köhler, Jacek Zatorski +6
The quest for the value of the electron's atomic mass has been subject of continuing efforts over the last decades. Among the seemingly fundamental constants which parameterize the…
The trap design of PENTATRAP
C. Roux, Ch. Böhm, A. Dörr +7
A novel Penning trap tower consisting of five compensated cylindrical Penning traps is developed for the PENTATRAP mass spectrometer at the Max-Planck-Institut für Kernphysik in He…
PENTATRAP: A novel cryogenic multi-Penning trap experiment for high-precision mass measurements on highly charged ions
J. Repp, Ch. Böhm, J. R. Crespo López-Urrutia +9
The novel five-Penning trap mass spectrometer PENTATRAP is developed at the Max-Planck-Institut für Kernphysik (MPIK), Heidelberg. Ions of interest are long-lived highly charged nu…
