“…Cerium is an element of interest for several scientific areas, requiring precise spectroscopic data. On the one hand, cerium may be employed in plasma-facing components [1], hence, can potentially evaporate to plasmas and be spectroscopically observed in plasma environments, such as in fusion reactors. On the other hand, cerium and other lanthanide elements have astrophysical significance [2][3][4].…”

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.
