Electron beam ion traps (EBITs) are ideal tools for both production and study of highly charged ions (HCIs). In order to reduce their construction, maintenance, and operation costs, we have developed a novel, compact, room-temperature design, the Heidelberg Compact EBIT (HC-EBIT). Four already commissioned devices operate at the strongest fields (up to 0.86 T) reported for such EBITs using permanent magnets, run electron beam currents up to 80 mA, and energies up to 10 keV. They demonstrate HCI… 

A low-energy compact Shanghai-Wuhan electron beam ion trap for extraction of highly charged ions.

In this work, the tungsten ions below the charge state of 15 have been produced, extracted, and analyzed and preliminarily indicates that the 549.9 nm line comes from W14+.

Electron-beam ion source/trap charge breeders at rare-isotope beam facilities

At accelerator facilities, charge breeders convert ion beams of low charge states (mostly singly charged) into multiply charged ion beams to extend the energy range of beams accelerated and delivered

Production of highly charged ions of rare species by laser-induced desorption inside an electron beam ion trap.

A novel, highly efficient technique for the injection of very rare species into electron beam ion traps (EBITs) for the production of highly charged ions (HCI) that relies on in-trap laser-induced desorption of atoms from a sample brought very close to the electron beam resulting in a very high capture efficiency in the EBIT.

A cryogenic radio-frequency ion trap for quantum logic spectroscopy of highly charged ions.

Using this trap in conjunction with an electron beam ion trap and a deceleration beamline, it is able to trap single highly charged Ar13+ (Ar XIV) ions concurrently with single Be+ ions, a key prerequisite for the first quantum logic spectroscopy of a HCI.

Abstract The ALPHATRAP experiment at the Max-Planck Institute for Nuclear Physics in Heidelberg aims at probing the validity of quantum electrodynamics in extremely strong electromagnetic fields. To

X-Ray Photoabsorption of Density-sensitive Metastable States in Ne vii, Fe xxii, and Fe xxiii

Metastable states of ions can be sufficiently populated in absorbing and emitting astrophysical media, enabling spectroscopic plasma-density diagnostics. Long-lived states appear in many

A compact electron-beam ion trap (EBIT) as a multiply charged ion source for medium Z, e.g., Ne10+, Ar18+, Kr26+, and so on, has been developed. A pair of NdFeB permanent magnets generates an intense

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.
