X-ray spectroscopy and ion extraction at the Dresden EBIT

The Dresden electron beam ion trap (EBIT) is a compact, long-term stable room-temperature EBIT able to produce bare nuclei for elements up to about Z = 30 and helium-like to neon-like ions for heavier elements, respectively. With ion species ranging from Ir57+ up to Ir62+ and Ce48+ we demonstrate the applicability of the ion source for energy and wavelength-dispersive X-ray spectroscopy. First ion extraction experiments show that it is possible to extract ion currents of 10(6) ions per pulse at various pulse repetition rates, measured electrically for xenon ion pulses with a mean ion charge of Xe40+ and a pulse FWHM of 15 mus. Additionally, first X-ray spectra from the interaction of extracted xenon ions with a carbon target are presented. (C) 2003 Elsevier Science B.V. All rights reserved.
