Abstract

The electron beam ion trap (EBIT) at Livermore produces very highly charged atomic ions by successive ionization in collisions with an intense (up to 120 mA, 4000 A/cm{sup 2}), energetic (up to 200 keV) electron beam. The ions are trapped radially in the electrostatic field of the electron beam. While it is on, and with the beam off by a 3-T magnetic field produced by a pair of superconducting Helmholtz coils. Axially, the ions are trapped by a bias potential on the top and bottom electrodes. The central electrode is 4.2 cm long and has a diameter of 1 cm. EBIT was originally designed as an X-ray source, and six slots allow direct line-of-sight radial access to the trapping for X-ray measurements. Spectra of highly-charged krypton were shown.

FT-ICR mass spectrometry of very highly charged atomic ions

Conference Schweikhard, L ; Beck, B ; Beiersdorfer, P

The authors report FT-ICR measurements of samples trapped in the electron beam ion trap (EBIT) at Livermore. They made use of the access provided by the radial x-ray slots. They constructed two probes that could be inserted into the 2-mm wide slots. The probes each subtend only 25{degree} and face each other 180{degree} apart. They show a typical transformed spectrum of highly charged {sup 84}Kr ions obtained with this system. The spectrum was obtained by exciting with a 300-{mu}s sweep from 17.5 to 19.5 MHz. The resonance peaks of {sup 84}Kr{sup 34+}, {sup 84}Kr{sup 35+}, and {sup 84}Kr{sup 36+} aremore » clearly visible.« less

Penning traps with unitary architecture for storage of highly charged ions

Journal Article Tan, Joseph N ; Guise, Nicholas D ; Brewer, Samuel M - Review of Scientific Instruments

Penning traps are made extremely compact by embedding rare-earth permanent magnets in the electrode structure. Axially-oriented NdFeB magnets are used in unitary architectures that couple the electric and magnetic components into an integrated structure. We have constructed a two-magnet Penning trap with radial access to enable the use of laser or atomic beams, as well as the collection of light. An experimental apparatus equipped with ion optics is installed at the NIST electron beam ion trap (EBIT) facility, constrained to fit within 1 meter at the end of a horizontal beamline for transporting highly charged ions.

High-resolution spectroscopic diagnostics of very high-temperature plasmas in the hard x-ray regime

Thesis/Dissertation Widmann, Klaus

Motivated by the need for establishing a reliable database useful for the application of x-ray spectroscopic tools for the diagnostic of very high temperature plasmas, high-resolution crystal spectrometer measurements have been performed investigating the characteristic K-shell radiation of highly charged krypton and xenon. The measurements, which have been performed at the Electron-Beam-Ion-Trap (EBIT) facility of the Lawrence Livermore National Laboratory, include the investigation of the n = 2 → 1 transitions in heliumlike krypton (Kr ³⁴⁺) and innershell excited lithiumlike krypton (Kr{sup 33+}) utilizing a conventional reflection-type crystal spectrometer of von Hamos geometry. The electron-excitation-energy selective measurements map the contributionmore »« less

Determination of the ReA Electron Beam Ion Trap electron beam radius and current density with an X-ray pinhole camera

Journal Article Baumann, Thomas M., E-mail: baumannt@nscl.msu.edu ; Lapierre, Alain ; Kittimanapun, Kritsada ; ... - Review of Scientific Instruments

The Electron Beam Ion Trap (EBIT) of the National Superconducting Cyclotron Laboratory at Michigan State University is used as a charge booster and injector for the currently commissioned rare isotope re-accelerator facility ReA. This EBIT charge breeder is equipped with a unique superconducting magnet configuration, a combination of a solenoid and a pair of Helmholtz coils, allowing for a direct observation of the ion cloud while maintaining the advantages of a long ion trapping region. The current density of its electron beam is a key factor for efficient capture and fast charge breeding of continuously injected, short-lived isotope beams. Itmore »« less

Measurement of charge exchange cross sections for highly charged xenon and thorium ions with molecular hydrogen in a Penning Ion Trap

Technical Report Weinberg, G. M.

Highly charged xenon (35+ to 46+) and thorium (72+ to 79+) ions were produced in an Electron Beam Ion Trap (EBIT). The ions were extracted from EBIT in a short pulse. Ions of one charge state were selected using an electromagnet. The ions were recaptured at low energy in a cryogenic Penning trap (RETRAP). As the ions captured electrons from molecular hydrogen, populations of the various charge states were obtained by measuring the image currents induced by the ions on the electrodes of the trap. Data on the number of ions in each charge state vs. time were compared tomore »« less
