A transportable setup for high resolution measurements of ion-atom collisions — •Simone Götz1, Bastian Höltkemeier1, Thomas Amthor1, Alexey Sokolov2, Wolfgang Quint2, and Matthias Weidemüller1 — 1Universität Heidelberg, Philosophenweg 12, 69120 Heidelberg — 2GSI Helmholtzzentrum für Schwerionenforschung GmbH, 64291 Darmstadt
We present a transportable setup combining a magneto-optical trap for rubidium atoms with a recoil ion momentum spectrometer. After interaction of the trapped atoms with highly charged ions the recoil ion momentum can be measured with very high precision due to the very low thermal spread of the target atoms. In collaboration with the GSI in Darmstadt we will investigate correlation effects in multiple charge transfer between the rubidium atoms and highly charged ions. We will discuss several improvements of this setup, including a new recoil ion momentum spectrometer with enhanced optical access and a new technique to calibrate the spectrometer by producing a high rate of short ion pulses from the trapped atoms based on an LED.
