A setup for the study of clusters from a magnetron sputter source by MR-ToF mass spectrometry — •Paul Florian Giesel, Paul Fischer, and Lutz Schweikhard — Institut für Physik, Universität Greifswald, 17487 Greifswald, Germany

The Greifswald multi-reflection time-of-flight (MR-ToF) mass-spectrometer experiment investigates the properties of atomic clusters. So far, a pulsed laser-ablation source has been used to produce cluster ions with sizes up to about ten atoms from a solid target without the use of aggregation gas. The setup has now been expanded by a magnetron sputter source capable of producing considerably larger clusters. In order to incorporate this new source, a linear Paul trap has been installed to accumulate and bunch the continuous ion beam for injection into the MR-ToF analyzer. First measurements to characterize the new components as well as the system’s capability to handle large clusters with masses up to 40,000 u have been performed.
