Ion mobility measurements are a powerful tool to investigate ion-atom interaction potentials. Their sensitivity to the electronic configuration has been demonstrated for many elements across the periodic table. Especially for heavy elements, the impact of relativistic effects on the electron configuration may lead to deviations in the periodicity, hence to distinct ion mobilities [Laatiaoui2012] as recently proven in the lanthanide region. A conceptual design for an ion mobility spectrometer is being developed to enable systematic ion mobility spectrometry also across the actinide series. Actinide ions will be created via a two-step photoionization in argon gas. This will allow an element-selective detection. In the talk, the current status and future plans are presented.
