P61.2 Large Volume Press - Extreme Conditions (LVP-EC)


News

  • 04-11-2017. The LVP beamline P61.2 was showcased on DESY day (Nacht des Wissens).
  • 16-10-2017. A 2 day Xtreme Conditions Workshop for PETRA IV took place.
  • 20-09-2017. Important notice! The LVP will be disconnected from 18 December 2017 until end of contruction of the concrete hutch walls.
  • 01-06-2017. The Large Volume Press (LVP) is fully operational and users can apply for standalone use (see menu).
  • 01-06-2017. The frontend and beamline are under construction and no X-rays are available. Estimated time of arrival of X-rays is projected for late 2018.

Experiments at extreme conditions using white-beam synchrotron radiation

The Large Volume Press (LVP) extreme conditions beamline will utilize synchrotron X-ray radiation with an energy range of 40 - 150 keV. The beamline is designed for the combination of ED-XRD, WD-XRD (with monochromatic light) and Radiography Imaging techniques. The physical and chemical properties, structure and composition of samples can be measured in situ using these techniques under extreme conditions of high pressures and temperatures. Various combinations and additional set ups are envisaged for the future.

The LVP that is installed at P61.2 is the world’s first 6-rams-LVP operated at a synchrotron facility. This type of instrument offers deformation capability, precise control of the anvil positions and high efficiency of pressure generation. Experiments at extreme conditions of high pressures and temperatures are possible in various modes using a combination of 6 first-stage anvils and 6 or 8 second-stage anvils (6-6 and 6-8 compression geometries, respectively). Using the 6-8 mode with tungsten carbide second stage anvils, pressures up to 30 GPa can be generated at the expense of a smaller anvil gap, up to 10 degrees for diffracted X-rays. Alternatively, the 6-6 mode offers a wider anvil gap, particularly up to 27 degrees in the vertical plane for diffracted X-rays, but the maximum sample pressure is limited to about 15 GPa. Also, controlled deformation of samples is only possible in 6-6 mode.

On this website you can find information about booking time on the LVP - at the moment without X-rays. Users are encouraged to prepare experiments as much as possible in advance and bring anvils with common truncation edge length (TEL). Notwithstanding, we can fully accommodate you in our sample preparation laboratory if you have no resources except for the sample you wish to synthesise at high P,T conditions.

Other information about the beamline can be found in the menus on the left. If you have any questions, please do not hesitate to contact me.

Sincerely,
Dr. Robert Farla, beamline manager.
