Optical diagnostic of nonneutral plasma of Pr⁺ ions confined in a rf trap — •Wojciech Koczorowski, Gustaw Szawiola, Adrian Walaszyk, Adam Buczek, Danuta Stefanska, and Ewa Stachowska — Chair of Atomic Physics, Poznan University of Technology, Nieszawska 13, PL-60-965 Poznan, Poland

The ion cloud in a quadrupole rf trap constitutes simply a confined plasma. There exist a few theoretical models, which describes such systems [1,2,3]. However, discrepancies between theory and experiment are still being observed. This contribution shows also evidence of such differences concerning the trapped rare earth element, e.g. Pr⁺. The experimental method used for plasma diagnostics is based on a standard laser induced fluorescence technique.

The presented work has been supported by the project of Poznan University of Technology BW 63-028/06.
