Coulomb crystallization of highly charged ions

Science, 2015
Highly charged ions in cold confines High-energy irradiation can strip many electrons away from individual atoms, producing ions with charges of +10 or more. However, many of the interesting properties of such highly charged ions are hard to study or exploit under the extreme conditions needed to prepare them. Schmöger

Radioactive decays of highly-charged ions

EPJ Web of Conferences, 2015
Access to stored and cooled highly-charged radionuclides offers unprecedented opportunities to perform high-precision investigations of their decays. Since the few-electron ions, e.g.

Nanoscale ion implantation using focussed highly charged ions

New Journal of Physics, 2020
We introduce a focussed ion beam (FIB) based ion implanter equipped with an electron beam ion source (EBIS), able to produce highly charged ions. As an example of its utilisation, we demonstrate the direct writing of nitrogen-vacancy centres in diamond ...

QED tests with highly charged ions [PDF]

Journal of Physics B: Atomic, Molecular and Optical Physics, 2019
Abstract The current status of bound state quantum electrodynamics calculations of transition energies for few-electron ions is reviewed. Evaluation of one and two body QED correction is presented, as well as methods to evaluate many-body effects that cannot be evaluated with present-day QED calculations ...

Surface charge compensation for a highly charged ion emission microscope [PDF]

Ultramicroscopy, 2004
A surface charge compensation electron flood gun has been added to the Lawrence Livermore National Laboratory (LLNL) highly charged ion (HCI) emission microscope. HCI surface interaction results in a significant charge residue being left on the surface of insulators and semiconductors.

Angular Distribution of Characteristic Radiation Following the Excitation of He-Like Uranium in Relativistic Collisions

Atoms, 2021
In this paper, we present an experimental and theoretical study of excitation processes for the heaviest stable helium-like ion, that is, He-like uranium occurring in relativistic collisions with hydrogen and argon targets.

QED theory of elastic electron scattering on hydrogen-like ions involving formation and decay of autoionizing states

Physical Review Research, 2020
We develop ab initio relativistic QED theory for elastic electron scattering on hydrogen-like highly charged ions for impact energies where, in addition to direct (Coulomb) scattering, the process can also proceed via formation and consequent Auger decay
