High-resolution cluster analysis by multi-reflection time-of-flight mass spectrometry — Paul Fischer¹, •Stefan Knauer¹, Gerrit Marx¹, Birgit Schabinger¹, Lutz Schweikhard¹, and Robert Wolf² — ¹Institut für Physik, Universität Greifswald, Felix-Hausdorff-Str. 6, 17489 Greifswald — ²ARC Centre of Excellence for Engineered Quantum Systems, School of Physics, The University of Sydney, NSW 2006 Australia

Multi-reflection time-of-flight (MR-ToF) devices [1] have established themselves as mass separators and spectrometers with high resolving powers and fast processing times. A MR-ToF analyzer built at Greifswald was installed at ISOLTRAP for the investigation of exotic nuclei [2]. Based on this design a further setup combining MR-ToF analyzer with a laser ablation source was constructed for atomic cluster research. The developments aim to provide samples of selected clusters for further investigations, such as cluster-laser interactions or photoelectron spectroscopy. A characterization of the setup and first experimental results will be presented.
