  • E9: The Fine Resolution Powder Diffractometer (FIREPOD) at BER II

    • Authors: Alexandra Franz, Andreas Hoser
      First page: 103
      Abstract: The E9 (FIREPOD) is an upgraded fine resolution powder diffractometer for elastic neutron scattering, obtaining high quality data sets for Rietveld analysis, structure solution and phase analysis under ambient conditions as well as in situ at low / high temperatures, magnetic fields, gas pressure and various atmospheres.

  • E4: The 2-Axis Diffractometer at BER II

    • Authors: Karel Prokes, Fabiano Yokoachiya
      First page: 104
      Abstract: The double-axis diffractometer E4 is operated by the Helmholtz-Zentrum Berlin. It is suited for magnetic structure determinations and parametric studies on single crystals in a wide range of external conditions. Pyrolytic graphite and germanium focusing monochromators offer two fixed neutron incident wavelengths of about 1.0*106 ncm-2s-1.

  • The variable polarization undulator beamline UE52 PGM nanocluster trap at
           BESSY II

    • Authors: Ruslan Ovsyannikov, Tobias Lau
      First page: 105
      Abstract: UE52 PGM nanocluster trap is a soft x-ray beamline at BESSY II that delivers an unfocussed low-divergence beam of variable polarization. Its characteristics are ideally suited for ion trap studies of magnetic properties.

  • AIM reference track - test site for V2X communication systems and
           cooperative ITS services

    • Authors: Tobias Frankiewicz, Alexander Burmeister
      First page: 106
      Abstract: Cooperative intelligent transport systems (C-ITS) based on Vehicle2X (V2X) communication are currently under development in the automotive industry and regarded to be in mass-production in the near future. In order to develop and test cooperative ITS services, the Institute of Transportation Systems of the German Aerospace Center (DLR) operates a large-scale test site in the city of Braunschweig, Germany. This research infrastructure facilitates test activities, measurements as well as evaluation activities for C-ITS in a real-life environment.

  • European Proximity Operations Simulator 2.0 (EPOS) - A Robotic-Based
           Rendezvous and Docking Simulator

    • Authors: Heike Benninghoff, Florian Rems, Eicke-Alexander Risse, Christian Mietner
      First page: 107
      Abstract: The European Proximity Operations Simulator (EPOS) 2.0 located at the German Space Operations Center (GSOC) in Oberpfaffenhofen, Germany, is a robotic based test facility of the German Aerospace Center (DLR) used for simulation of rendezvous and docking (RvD) processes. Hardware such as rendezvous sensors (cameras, laser scanners) or docking tools, as well as software (e.g. for navigation and control) can be tested and verified. The facility consists of two robotic manipulators with each six degrees of freedom, a linear slide of 25m length on which one robot can be moved in the laboratory, and a computer-based monitoring and control system. EPOS 2.0 allows for real-time simulations of the rendezvous and docking process during the most critical phase (separation from 25m to 0m) of proximity and docking/berthing operations.

  • STG-ET: DLR electric propulsion test facility

    • Authors: Andreas Neumann
      First page: 108
      Abstract: DLR operates the High Vacuum Plume Test Facility Göttingen – Electric Thrusters (STG-ET). This electric propulsion test facility has now accumulated several years of EP-thruster testing experience. Special features tailored to electric space propulsion testing like a large vacuum chamber mounted on a low vibration foundation, a beam dump target with low sputtering, and a performant pumping system characterize this facility. The vacuum chamber is 12.2m long and has a diameter of 5m. With respect to accurate thruster testing, the design focus is on accurate thrust measurement, plume diagnostics, and plume interaction with spacecraft components. Electric propulsion thrusters have to run for thousands of hours, and with this the facility is prepared for long-term experiments. This paper gives an overview of the facility, and shows some details of the vacuum chamber, pumping system, diagnostics, and experiences with these components.

  • AIM in-vehicle platform for ITS services

    • Authors: Claus Kaschwich, Lars Wölfel
      First page: 109
      Abstract: The application platform for intelligent mobility (AIM) is a large scale research infrastructure operated by the Institute of Transportation System of the German Aerospace Center (DLR) in the city and region of Braunschweig. The in-vehicle platform for ITS services (ITS, Intelligent Transportation Systems) is an integral part of this large-scale research facility. The in-vehicle platform for ITS services can be seen as a modular kit which enables up to 50 vehicles to take part in a Vehicle-to-Vehicle and Vehicle-to-Infrastructure (V2X) communications in test sites like the V2X reference track in the city of Braunschweig. The in-vehicle platform for ITS services along with its integration into the AIM test field provides answers to a broad set of research questions in the Field of V2X communications on public roads. For example effects can be analyzed, which take place when vehicles with mixed equipped communication technologies are sharing one road.

  • Manned submersible „JAGO“

    • Authors: Karen Hissmann, Jürgen Schauer
      First page: 110
      Abstract: The manned submersible „JAGO“ is a human occupied underwater vehicle (HOV) designed for personal exploration and research in all types of aquatic systems and habitats. The seafloor along the continental shelf and slopes within the ocean twilight zone is JAGO’s main target area. The DNV-GL classed 2-person submersible has a maximum operating depth of 400 m. The two occupants, the pilot and one observer, are seated at 1 Atmosphere in a steel pressure hull with two large acrylic windows. The submersible’s small size and lightweight construction (3 T) allows worldwide operations from on board a wide variety of vessels as well as transport in a single standard 20-foot container together with all support equipment. Typical applications include personal observation of the sea bed and water column, video and photo documentation, selective non-intrusive sampling, placement of sensors and experiments, underwater inspection, as well as location and recovery of objects
