Welcome to the HZB User Facility BESSY II

The Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) operates the large scale research facility BESSY II, a third generation synchrotron source on Wilhelm-Conrad-Röntgen-Campus in Berlin-Adlershof. BESSY II provides ultrabright photon beams from the long wavelength Terahertz region to hard X-rays with complete control of the polarization of the radiation and energy range. The combination of brightness and time resolution makes BESSY II the ultimate microscope for time and space, since both femtosecond time and picometer spatial resolutions are available. In addition, HZB is home to a number of state-of-the-art on-site laboratories and CoreLabs. All these research facilities are designed to serve researchers from universities, foreign research institutions and industry.

IMPORTANT USER INFORMATION

To slow down the spread of the coronavirus SARS-CoV-2 we have decided to impose some restrictions:

  • We have resumed operation at the HZB step by step from the 4th of May 2020
  • Only HZB inhouse use working in the BESSY II experimental hall is allowed (please note the rules)
  • Operation of BESSY II for external users will remain suspended until June
  • Since we have to ensure, that sufficient distance is possible and practicable in the BESSY II experimental hall a “thinned out timetable” is in place. Only selected beamlines are accessable at a time
  • Please refer to the Corona-Special-Schedule for more details (schedule update regularly). If the beamline does not have a “green slot” or a “light green slot”, please stay away from the experiment (except from cases of emergency)
  • All beamtimes cancelled due to COVID-19 will be re-scheduled after the summer shut-down
  • All events will be cancelled until the end of July

FAST TRACK ACCESS for SARS-CoV-2 proposal

In light of the rapidly changing situation world-wide resulting from the SARS-CoV-2 virus BESSY II would like to ensure that it is doing everything possible to support researchers in their efforts to discover more about the virus and bring us closer to an effective vaccine or treatment. We are offering priority fast track access for groups who require instrument time for projects directly related to SARS-CoV-2. In order to submit a proposal for SARS-CoV-2 related research please contact us by email. More detailed information about our service at BESSY II can be found here.

Science Highlights

SCIENCE HIGHLIGHT
Catalysts: Efficient hydrogen production via structure In order to produce regenerative hydrogen efficiently by electrolysis of water, researchers also investigate perovskite oxides. Dr. Marcel Risch has been invited to publish an overview article.
SCIENCE HIGHLIGHT
Future information technologies: 3D Quantum Spin Liquid revealed An international team led by HZB scientists has investigated crystals of PbCuTe2O6 with neutron experiments at ISIS, NIST and ILL. They found spin liquid behaviour in 3D, due to a so called hyper hyperkagome lattice.
SCIENCE HIGHLIGHT
On the road to non-toxic and stable perovskite solar cells To replace lead by less toxic elements is not easy since lead-free perovskites show lower stability and poor efficiencies. Now, an international collaboration has engineered a new hybrid perovskite material with promising efficiency and stability.
SCIENCE HIGHLIGHT
User research at BESSY II: Insights into the visual perception of plants Plants use light not only for photosynthesis. Although the plant cell does not have eyes, it can still perceive light and thus its environment. Phytochromes, certain turquoise proteins, play the central role in this process.
SCIENCE HIGHLIGHT
User research at BESSY II: How new materials increase the efficiency of direct... A group from Brazil and an HZB team have investigated a novel composite membrane for ethanol fuel cells. It consists of the polymer Nafion, in which nanoparticles of a titanium compound are embedded by the rarely explored melt extrusion process.
SCIENCE HIGHLIGHT
New interaction between light and matter discovered at BESSY II A German-Chinese team from the MPI for Intelligent Systems has discovered a new interaction between light and matter at BESSY II. They succeeded in creating nanometer-fine magnetic vortices, so called skyrmions.
