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.
