  • A compact high-resolution X-ray ion mobility spectrometer 
    Reinecke, Tobias; Kirk, Ansgar T.; Heptner, Andre; Niebuhr, D.; Böttger, S.; Zimmermann, Stefan (College Park, MA : American Institute of Physics (AIP), 2016)
    For the ionization of gaseous samples, most ion mobility spectrometers employ radioactive ionization sources, e.g., containing 63Ni or 3H. Besides legal restrictions, radioactive materials have the disadvantage of a constant ...
  • Deceleration, precooling, and multi-pass stopping of highly charged ions in Be+ Coulomb crystals 
    Schmöger, L.; Schwarz, M.; Baumann, T.M.; Versolato, O.O.; Piest, B.; Pfeifer, T.; Ullrich, J.; Schmidt, Piet O.; Crespo López-Urrutia, J.R. (College Park, MD : American Institute of Physics, 2015)
    Preparing highly charged ions (HCIs) in a cold and strongly localized state is of particular interest for frequency metrology and tests of possible spatial and temporal variations of the fine structure constant. Our versatile ...
  • Efficient sympathetic motional-ground-state cooling of a molecular ion 
    Wan, Yong; Gebert, Florian; Wolf, Fabian; Schmidt, Piet O. (College Park, MD : American Physical Society, 2015)
    Cold molecular ions are promising candidates in various fields ranging from precision spectroscopy and test of fundamental physics to ultracold chemistry. Control of internal and external degrees of freedom is a prerequisite ...
  • Investigation of target erosion profiles sputter-eroded by a low-energy broad ion beam 
    Sakiew, Wjatscheslaw; Klocke, Eileen; Ristau, Detlev (New York, NY : American Inst. of Physics, 2021)
    The demand for ion beam sputtering (IBS) coated substrates is growing. In order to find new fields of application for IBS coating technology, it is necessary to understand in detail the distributions of the involved particles ...
  • Prevention of laser damage precursors in spaceborne ultraviolet antireflection coatings 
    Alig, Thimotheus; Bartels, Nils; Allenspacher, Paul; Balasa, Istvan; Böntgen, Tammo; Ristau, Detlev; Jensen, Lars (Washington, DC : Optica, 2021)
    In order to enhance the reliability and performance of space-based Lidar systems, it is desirable to increase the damage resistance of ultraviolet antireflective coatings. For laser pulses with nanosecond pulse duration, ...
  • Spatial separation effects in a guiding procedure in a modified ion-beam-sputtering process 
    Malobabic, Sina; Jupé, Marco; Ristau, Detlev (London : Nature Publishing Group, 2016)
    Cloud computing is a paradigm in which information is permanently stored in servers on the Internet and cached temporarily on clients. Virtual private network (VPN) is the most widely used technology for secure cloud access. ...
