“…Therefore, spectroscopy data for highly charged ions (HCI) of this element is needed for accurate interpretation of spectra emitted by ion sources [7]. For example, the observation of emissions from HCI of cerium and iridium impurities arising from a cathode with the same material has been reported [8], in a main magnetic focus ion source. Emission of HCI of cerium were also reported in an EBIT from contamination arising from a similar cathode [9].…”

We explore the Dielectronic Recombination structures at the Electron Beam Ion Trap at Jagiellonian University in Cracow, emited by cerium that is produced by the high-current cathode made of iridium and cerium. Small amounts of these elements evaporate from the cathode and form low-intensity admixtures within the electron-ion plasma in the EBIT. Their presence and specific ionic population can be observed by examining the spectral characteristics resulting from the DR process. Results have been compared with Flexible Atomic Code calculations, working in Unresolved Transition Array mode, providing identification of the charge states. Here we show that this mode provides quick calculations of very complex data with enough reliability for experimental comparison. These observations highlight which DR features and corresponding charge states that should be present in spectra obtained in EBITs with similar cathode specifications.

We present results for the production of highly charged ions in a rippled electron beam propagating in a multi-section drift tube with different electrostatic potentials in an axial magnetic focusing field. The inner-shell ionization of target atoms by electron impact occurs in local ion traps formed at the electron-beam crossovers. The utmost electron current density achieved is assessed at ~10 kA/cm2. The successive ionization of cathode materials and working substances such as xenon and bismuth was investigated as a function of the confinement time. The characteristic X-ray radiation from ions including Ir62+, Ce48+, Xe46+, and Bi60+ was detected. It is shown that it is possible to extract highly charged ions from local ion traps for a certain geometry of the drift tube structure and a certain distribution of the electric potentials.
