KMC-2: an X-ray beamline with dedicated diffraction and XAS endstations at BESSY II
Full text linkThe KMC-2 beamline is dedicated to provide X-ray radiation with high energy stability and resolution. The experimental setup is optimized towards offering a wide range of methods and sample environments. Two permanent endstations can be used in alternation. DIFFRACTION is a flexible multi-purpose diffractometer, based on a Huber six circle diffractometer in psi geometry. XANES provides the possibility for EXAFS, XANES and X-ray fluorescence measurements at-air
XPP: X-ray Pump Probe station at BESSY II
Full text linkThe X-ray Pump-Probe (XPP) experimental station predominantly aims at investigating hard and soft matter under a broad range of ambient conditions using time-resolved X-ray diffraction
FEI Helios NanoLab 460F1 FIB-SEM
Full text linkThe FEI Helios NanoLab 460F1 is a highly advanced dual beam FIB-SEM platform for imaging and analytical measurements, transmission electron microscopy (TEM) sample and atom probe (AP) needle preparation, process development and process control. For these purposes, the FEI Helios NanoLab 460F1 combines an ElstarTM UC technology electron column for high-resolution and high material contrast imaging with the high-performance TomahawkTM ion column for fast and precise sample preparation. The FEI Helios NanoLab 460F1 is additionally equipped with the MultiChemTM gas delivery system, an EasyLiftTM nanomanipulator, a cooling trap, an inert gas transfer (IGT) holder loadlock, a quick loader, a FlipStage 3TM, an EDX-System and an STEM III detector. This instrument is one of the few dual beam systems which combine an IGT holder loadlock with a FlipStage 3+TM EasyLiftTM nanomanipulator. Typical examples of use and technical specifications for the instrument are given below
HELGES: Helmholtz Laboratory for the Geochemistry of the Earth Surface
Full text linkNew developments in Geochemistry during the last two decades have revolutionized our understanding of the processes that shape Earth's surface. Here, complex interactions occur between the tectonic forces acting from within the Earth and the exogenic forces like climate that are strongly modulated by biota and, increasingly today, by human activity. Within the Helmholtz Laboratory for the Geochemistry of the Earth Surface (HELGES) of the Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences, it is our goal to quantify the rates and fluxes of these processes in detail and to develop new techniques to fingerprint them over various temporal and spatial scales. We use mass spectrometry facilities to analyze metal stable isotopes, element concentrations and cosmogenic nuclides to fingerprint and quantify geomorphological changes driven by erosion and weathering processes. We use these novel geochemical tools, to quantify, for example, the recycling of metals in plants after their release during weathering of rocks and soils, soil formation and its erosion rates, and mechanisms and speed of sediment transport through drainage basins. Our research is thus dedicated towards understanding material turnover rates at the Earth's surface by using geochemical fingerprints
FEMTOSPEX Molecules and Surfaces: Electron spectroscopy setup for time-resolved laser-pump/ X-ray-probe experiments at BESSY II
Full text linkThe flexible end station “FEMTOSPEX Molecules and Surfaces”, which will enable time resolved photoemission studies in the future at HZB, is presented
Hydrothermal Laboratory
Full text linkThe hydrothermal laboratory is equipped with horizontal and vertical cold-seal pressure vessels for the synthesis of crystals or glasses or to study interactions between minerals/rocks, melts, and fluids at hydrostatic conditions. An advantage is that long-term runs can be done to investigate equilibria between solid phases. This facility, operated by the Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences, is open to all academic applicants, both national and international. There is no external steering board. Requests to use the laboratory are evaluated based on scientific quality and feasibility of the project
The MX beamlines BL14.1-3 at BESSY II
Full text linkThe Macromolecular Crystallography (MX) group at the Helmholtz-Zentrum Berlin (HZB) is operating three state-of-the-art synchrotron beamlines for MX at BESSY II in Berlin (Heinemann et al., 2003; Mueller et al., 2012, 2015). The radiation source for all three beamlines BL14.1-3 is a superconducting 7T-wavelength shifter. Currently, the three beam lines are the most productive stations for MX in Germany, with about 250 PDB depositions per year and over 1500 PDB depositions in total (Status 10/2015). BL14.1 and BL14.2 are energy tuneable in the range 5.5-15.5 keV, while beam line BL14.3 is a fixed-energy side station operated at 13.8 keV. The HZB-MX beamlines are in regular user operation providing close to 200 beam days per year and about 600 user shifts to approximately 100 research groups across Europe. Additional user facilities include office space adjacent to the beam lines, a sample preparation laboratory, a biology laboratory (safety level 1) and high-end computing resources
FEI Titan 80-300 STEM
Full text linkThe FEI Titan 80-300 STEM is a scanning transmission electron microscope equipped with a field emission electron gun, a three-condenser lens system, a monochromator unit, and a Cs probe corrector (CEOS), a post-column energy filter system (Gatan Tridiem 865 ER) as well as a Gatan 2k slow scan CCD system. Characterised by a STEM resolution of 80 pm at 300 kV, the instrument was one of the first of a small number of sub-ångström resolution scanning transmission electron microscopes in the world when commissioned in 2006
The 7T-MPW-EDDI beamline at BESSY II
Full text linkThe materials science beamline EDDI is operated in the Energy Dispersive DIffraction mode and provides hard synchrotron X-rays in an energy range between about 8 … 150 keV for a multitude of experiments reaching from the in-situ study of thin film deposition over the investigation of liquid phase processes to the analysis of the residual stress distribution in complex components and technical parts. For high temperature experiments or measurements under external mechanical load various devices such as heating stations and a tensile/compression load test rig are available. Besides the sample environment for pure diffraction experiments a tomography/radiography setup is provided which allows for combined simultaneous diffraction plus imaging investigations
FEI Titan 80-300 TEM
Full text linkThe FEI Titan 80-300 TEM is a high-resolution transmission electron microscope equipped with a field emission gun and a corrector for the spherical aberration (CS) of the imaging lens system. The instrument is designed for the investigation of a wide range of solid state phenomena taking place on the atomic scale, which requires true atomic resolution capabilities. Under optimum optical settings of the image CS-corrector (CEOS CETCOR) the point-resolution is extended up to the information limit of well below 100 pm with 200 keV and 300 keV electrons. A special piezo-stage design allows ultra-precise positioning of the specimen in all 3 dimensions. Digital images are acquired with a Gatan 2k x 2k slow-scan charged coupled device camera
