  • A transportable optical lattice clock for metrology and geodesy 
    Grotti, Jacopo (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    This work presents the first measurement campaigns performed with PTB transportable optical lattice clock based on Strontium atoms for applications in clock comparisons and relativistic geodesy.
  • An aluminum optical clock setup and its evaluation using Ca+ 
    Kramer, Johannes Albrecht (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2023)
    This thesis reports about the progress of the aluminum ion clock that is set up at the German National Metrological Institute, Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig. All known relevant systematic ...
  • Controlling motion in quantum logic clocks 
    Wübbena, Jannes Bernhard (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2014)
    [no abstract]
  • Entwicklung einer Low-Level-Radon-Referenzkammer 
    Linzmaier, Diana (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2013)

  • The gravity field in force standard machines 
    Schilling, Manuel; Timmen, Ludger; Kumme, Rolf (Helsinki : IMEKO, 2017-06-01)
    The gravity acceleration g plays an important role in several physical quantities as provided by National Metrology Institutes. The unit of force is realized in dependence on g in force standard machines (FSM). We present ...
  • Traceability of the Hannover FG5X-220 to the SI units 
    Schilling, Manuel; Timmen, Ludger (Cham : Springer, 2016-06-28)
    The absolute measurement of g is currently realized through the laser interferometric measurement of a free falling retro-reflector. The Micro-g LaCoste FG5X is a free-fall gravimeter with a laser interferometer in ...
