A transportable setup for investigation of multiple charge transfer — •Simone Götz1, Bastian Höltkemeier1, Matthias Weidemüller1, and Brett DePaola21Philosophenweg 12, 69126 Heidelberg — 2Kansas State University, Kansas, USA

We report on a transportable compact setup combining a dark SPOT (spontaneous optical trap) for Rubidium atoms with a recoil ion momentum spectrometer [1]. The target is loaded with high flux from a 2 dimensional magneto-optical trap, achieving densities of up to 1011 atoms/cm−3. The spectrometer is characterized measuring the ion recoil energy in photoionization of the trapped atoms [2,3].

In collaboration with the GSI in Darmstadt this setup will be used to investigate correlation effects in multiple charge transfer between the rubidium atoms and highly charged ions. An outlook will be given.
