Recent Developments in MaMFIS Technology for the Production of Highly Charged Ions

We present results for the production of highly charged ions in a rippled electron beam propagating in a multi-section drift tube with different electrostatic potentials in an axial magnetic focusing

The Search for Variation of Fundamental Constants with Clocks

In many theories beyond the Standard Model the quantities that we call “fundamental constants” become space‐time dependent, leading to corresponding variation of atomic and molecular spectra and

Considerations towards the possibility of the observation of parity nonconservation in highly charged ions in storage rings

The feasibility of an experiment for the observation of parity nonconserving effects using He-like highly charged ions in storage rings is discussed theoretically. The basic idea is the observation

Highly charged ions: Optical clocks and applications in fundamental physics

Electronic states of highly charged ions show magnified fine-structure, Lamb shift, and hyperfine effects making them sensitive probes of bound-state quantum electrodynamics and nuclear physics.

Ionization-Excitation of helium-like ions by high-energy electrons

The differential and total cross sections are calculated for the ionization of helium-like ions that is accompanied by the excitation of residual ions to ns states owing to an electron impact.

A very low energy compact electron beam ion trap for spectroscopic research in Shanghai.

The design of this EBIT allows adjustment of the electron gun's axial position in the fringe field of the central magnetic field, particularly important for low electron beam energy operation, since the magnetic field strength is not tunable with permanent magnets.

Development of a small and versatile electron beam ion source using a permanent magnet

Compact electron beam ion trap for spectroscopy of moderate charge state ions.

A compact electron beam ion trap has been constructed for spectroscopic studies of moderate charge state ions and a superconducting wire with a high critical temperature is used for the central magnet so that it can be operated without liquid helium.

A compact, versatile low-energy electron beam ion source.

In ion extraction experiments, a stable production of low and intermediate charged ions at electron beam energies below 2 keV is demonstrated and X-ray spectroscopy measurements confirm the possibility of using the Dresden EBIT-LE as a source of X-rays from ions excited at low electron energies.

Evaporative cooling of highly charged dysprosium ions in an enhanced electron-beam ion trap.

Computer simulations of evaporative cooling in superEBIT indicate that with the use of neon, nitrogen, or helium coolants, significant amounts of bare and hydrogenlike dysprosium ions can be trapped indefinitely for the observation of bound-state {beta} decay.
