Abstract
Highly charged ions are used in basic investigations to study problems in atomic and plasma physics. Further on, the application of highly charged ions in materials research and other fields as nanomechanics and information techniques grew significantly in the last years. In the present paper, we report on results derived with a warm electron beam ion trap (WEBIT) that works without any cryogenic equipment. A special source construction allows to generate dense electron beams at room temperature with a current density of up to 240 A cm −2 and an acting ionization factor of (2⋯5)×10 21 cm −2 . Ions like Ar 17+, Xe 44+ and Ir 65+ were detected by X-ray spectroscopy. A charge capacity of about 8×10 7 elementary charges of the trap is estimated.
