Investigation of metal clusters by multi-reflection time-of-flight mass spectrometry — •Paul Fischer1, Gerrit Marx1, Madlen Müller1, Birgit Schabinger1, Lutz Schweikhard1, Florian Simke1, and Robert Wolf2 — 1Institut für Physik, Universität Greifswald — 2ARC Centre of Excellence for Engineered Quantum Systems, School of Physics, The University of Sydney
Multi-reflection time-of-flight mass spectrometers (MR-ToF MS) are successfully employed for ion investigation and separation, offering advantages e.g. in the study of short-lived radionuclides due to their high mass resolving power and comparatively short measurement time [1,2].
A MR-ToF analyzer recently built at Greifswald has been combined with a laser-ablation/ionization source. Different types of metal clusters - compositions of multiple atoms of the ablated material - have been studied by use of conventional ToF and MR-ToF operation. The experimental results illustrate the possibilities of cluster production and investigation with the new system.
