We present a transportable setup combining a dark SPOT (spontaneous optical trap) for Rubidium atoms with a recoil ion momentum spectrometer [1]. The very low thermal spread of the atoms in the trap, allows to measure the atom recoil momenta after interaction with photons or highly charged ions with very high precision. In collaboration with the GSI in Darmstadt we will investigate correlation effects in multiple charge transfer between the Rubidium atoms and highly charged ions.
In addition to the recoil ion momentum spectrometer with high resolution we discuss several other improvements of our setup, including enhanced optical access and a new mechanism for efficient loading of the magneto-optical trap with high flux.
