First Results of Ion Trapping in the Dresden EBIT II
With the Dresden EBIT it is possible to produce highly charged ions in a compact, economical and long-term stable ion source working at room temperature. The operation principle is based on electron impact ionization of primarily neutral atoms in a high-density electron beam in combination with electrical potentials for axial trapping. Radial trapping is realized by the negative space charge of the electron beam itself. After build-up the first Dresden EBIT in 1999 first results from a second EBIT device, the so-called Dresden EBIT II are presented. By means of X-ray spectroscopy we analyze the influence of different source parameters as ion trapping time, height of wall potentials and pressure on the production and storage of highly charged xenon ions.
