Sympathetic cooling of charged particles in Penning traps using electron cyclotron radiation
Jost Herkenhoff, Jonathan Notter, Klaus Blaum
We present a new technique for cooling arbitrary charged particles in a Penning trap by utilizing self-cooled electrons stored in a separate, macroscopically distant Penning trap a…
Nonlinear calcium King plot constrains new bosons and nuclear properties
A. Wilzewski, L. I. Huber, M. Door +39
Nonlinearities in King plots (KP) of isotope shifts (IS) can reveal the existence of beyond-Standard-Model (BSM) interactions that couple electrons and neutrons. However, it is cru…
Probing new bosons and nuclear structure with ytterbium isotope shifts
Menno Door, Chih-Han Yeh, Matthias Heinz +24
In this Letter, we present mass-ratio measurements on highly charged Yb ions with a precision of and isotope-shift measurements on Yb on the …
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…
Atomic mass determination of uranium-238
Kathrin Kromer, Chunhai Lyu, Jacek Bieroń +10
The atomic mass of uranium-238 has been determined to be , improving the literature uncertainty by two orders of magnitude. It is obtained from a m…
Fast Silicon Carbide MOSFET based high-voltage push-pull switch for charge state separation of highly charged ions with a Bradbury-Nielsen Gate
Christoph Schweiger, Menno Door, Pavel Filianin +8
In this paper we report on the development of a fast high-voltage switch, which is based on two enhancement mode N-channel Silicon Carbide Metal Oxide Semiconductor Field-Effect Tr…
Observation of a low-lying metastable electronic state in highly charged lead by Penning-trap mass spectrometry
Kathrin Kromer, Chunhai Lyu, Menno Door +10
Highly charged ions (HCIs) offer many opportunities for next-generation clock research due to the vast landscape of available electronic transitions in different charge states. The…
High-precision determination of factors and masses of and
F. Heiße, M. Door, T. Sailer +13
We present the measurements of individual bound electron factors of and on the relative level of per billion. Th…
High-precision mass measurement of doubly magic Pb
Kathrin Kromer, Chunhai Lyu, Menno Door +10
The absolute atomic mass of Pb has been determined with a fractional uncertainty of by measuring the cyclotron-frequency ratio of Pb…
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…
