摘要

The electron beam ion trap (EBIT), and the higher-energy Super EBIT at Lawrence Livermore National Laboratory can produce any highly charged ion. These highly charged ions are used in a variety of research programs. Recent results from four different experiments are reviewed here. K-shell ionization cross sections have been measured for the hydrogenlike ions of several elements, and L-shell ionization cross sections have been measured for uranium ions. A measurement of the ground-state hyperfine transition in hydrogenlike (sup 165)H(sup 66+) is notable because of the complete absence of Doppler shifts. A cryogenic Penning trap, injected with EBIT ions, has been used to observe a single highly charged ion as it recombines by sequential electron capture from H(sub 2) gas. A large sputtered ion yield, suggesting a surface Coulomb explosion, has been observed from insulators bombarded with very highly charged EBIT ions. 21 refs., 11 figs.
