Ion charge states of 3d metal ions in the electron beam of the Dresden electron beam ion trap (EBIT), a room-temperature EBIT, are determined by x-ray spectroscopy. It is shown that ions of highest charge states as bare nuclei and hydrogen- and helium-like ions can be produced with ion densities of about 105 cm−3 up to 108 cm−3 in the trap. The Dresden EBIT operates at a typical working gas pressure region of 10−8 mbar down to 10−10 mbar. Thus the influence of the realized working gas pressure on the derived ion charge state distribution is investigated by model calculations. © 2002 American Institute of Physics.
