Title: Extraction of highly charged ions from the Berlin Electron Beam Ion Trap for interactions with a gas target

Abstract

Highly charged ions are extracted from the Berlin Electron Beam Ion Trap for investigations of charge exchange with a gas target. The classical over-the-barrier model for slow highly charged ions describes this process, whereby one or more electrons are captured from the target into Rydberg states of the ion. The excited state relaxes via a radiative cascade of the electron to ground energy. The cascade spectra are characteristic of the capture state. We investigate x-ray photons emitted as a result of interactions between Ar{sup 17+} ions at energies {<=}5q keV with Ar atoms. Of particular interest is the velocity dependence of the angular momentum capture state l{sub c}.

  • The high-energy electron beam ion trap SuperEBIT at the Lawrence Livermore National Laboratory allows the study of the x-ray emission from highly charged ions interacting with electrons with energy in excess of 200 keV. Radiation from ions as highly charged as Cf96+ has been produced this way. The facility is being used to investigate the contributions from quantum electrodynamics in heavy ions. Here the focus is lithiumlike ions, especially U89+, which provide the opportunity for the most accurate test of QED in highly charged ions. We have also used the facility to measure the degree of x-ray line polarization asmore » a function of the energy of the electron collision energy. For example, we have studied the linear polarization of the K-shell emission lines of Fe24+ for electron-impact energies high as 120 keV. A new area of research is the investigation of nuclear excitation by electronic transitions. This is the inverse process of internal conversion, where an atomic x ray is absorbed by the nucleus resulting in an excited nuclear state. We are planning to study this process in 189Os using 217 keV atomic x rays generated in the interaction with a 196 keV electron beam.« less
  • Highly charged Ar (up to 18+), Xe (up to 48+), and U (up to 71+) ions produced through electron-impact ionization and excitation in an electron-beam ion trap have efficiently been extracted from the trap, and mass and charge analyzed. Charge-state distributions for Ar and Xe ions following electron-impact ionization and excitation have been measured. Relative yields for the production of Ar{sup 16+} and Xe{sup 44+} ions have been deduced as a function of electron-beam energies. Ar {ital K} and Xe {ital L} x-ray emission following Ar{sup 17+}, Ar{sup 18+} and Xe{sup 44+}, Xe{sup 45+} and Xe{sup 48+} ion impact onmore » a Cu surface was measured. The observed line positions demonstrate electron capture into high-{ital n} states and a fast radiative decay in the neutralization process at the surface.« less
  • We describe results from highly ion extraction experiments at the Electron Beam Ion Trap (EBIT) facility which is now operated at Lawrence Berkeley National Laboratory after transfer from Lawrence Livermore National Laboratory. Requirements on ion source performance for the application of highly charged ions (e. g. Xe{sup 44+}) in surface analysis and materials science are discussed.
  • Systematic variation of the electron-beam energy in an electron-beam ion trap has been employed to produce soft-X-ray spectra of Os, Bi, Th, and U with highest charge states ranging up to Ni-like ions. Guided by relativistic atomic structure calculations, the strongest lines have been identified with {Delta}n = 0 (n = 4 to n' = 4) transitions in Rb- to Cu-like ions. The rather weak 4p-4d transitions are much less affected by QED contributions than the dominant 4s-4p transitions. Our wavelength measurements consequently provide benchmarks with and (almost) without QED. Because the radiative corrections are not very sensitive to themore » number of electrons in the valence shell, our data, moreover, provide benchmarks for the evaluation of electron-electron interactions.« less
  • An electron-beam ion trap (EBIT) has just been completed in the Clarendon Laboratory, Oxford. The design is similar to the devices installed at the Lawrence Livermore National Laboratory. It is intended that the Oxford EBIT will be used for x-ray and UV spectroscopy of hydrogenic and helium-like ions, laser resonance spectroscopy of hydrogenic ions and measurements of dielectronic recombination cross sections, in order to test current understanding of simple highly charged ions.
