Resonance ionization scheme development at ISOLDE RILIS — •Katerina Chrysalidis^1,2, Jochen Ballof^1,2, Thomas Day Goodacre^1,3, Valentin Fedosseev¹, Bruce Marsh¹, Sebastian Rothe¹, Christoph Seiffert¹, and Klaus Wendt² — ¹CERN, Geneva, Switzerland — ²JGU, Mainz, Germany — ³University of Manchester, Manchster, United Kingdom

The RILIS at the ISOLDE radioactive beam facility at CERN is the most intensively used ion source, providing more than >75 % of ion beams in 2016. Based on the stepwise laser resonance ionization, the RILIS offers an element selective process of ionization. Each element possesses a unique atomic configuration, requiring a specific laser ionization scheme. The stepwise ionization additionally offers the means to ionize the atom via high lying Rydberg states. This method allows for the determination of the ionization potential of an element.
An overview over the currently available laser ionization schemes and the latest scheme development will be given alongside the discussion of the measurement of the europium ionization potential. Furthermore, an outlook towards future developments and applications of the ISOLDE RILIS will be given.
