Production of C4+ in an EBIS for collinear laser spectroscopy — •Emily Burbach1, Phillip Imgram2, Kristian König1, Bernhard Maaß1, Patrick Müller1, and Wilfried Nörtershäuser1 — 1Institut für Kernphysik, TU Darmstadt, Germany — 2Instituut voor Kern- en Stralingsfysica, KU Leuven, Belgium
The Collinear Apparatus for Laser Spectroscopy and Applied Science (COALA) at the Technical University of Darmstadt was used to measure the 1s2s 3S1→ 1s2p 3PJ 227 nm transitions of C4+ to improve ab-initio atomic structure calculations [1]. To obtain an ion beam suitable for laser spectroscopy, production of Cn+ in an electron beam ion source (EBIS) was tested with the gases propane (C3H8), methane (CH4) and carbon dioxide (CO2).
We present results from collinear laser spectroscopy with differently produced continuous and pulsed C4+ ion beams. Wienfilter analyses facilitate understanding the ion production processes for different gas compounds.
This project is supported by DFG (Project-ID 279384907 - SFB 1245).
