Agreement signed: Three neutron instruments will be transferred to the Polish research reactor MARIA in 2019
Agreement signed: HZB and NCBJ agreed to transfer and rebuild three of HZB’s neutron scattering instrumentsin 2019.
In February 2017 Helmholtz-Zentrum Berlin (HZB) and the National Centre for Nuclear Research (NCBJ) in Poland agreed to transfer and rebuild three of HZB’s neutron scattering instruments at the Polish research reactor MARIA in 2019. With support from the Polish Ministry of Science and Higher Education, the facility near Warsaw is currently being upgraded with latest generation technology, offering attractive research opportunities for neutron scientists from Germany and Europe.
After authorization by the Supervisory Board of HZB, the management of HZB agreed to the transfer of the neutron instruments E4 (2-axis diffractometer), E5 (4-circle diffractometer) and E6 (focusing powder diffractometer) to the Polish research reactor MARIA. At present the instruments are still located in the experimental hall of the research reactor BER II. They are currently operated for research co-operations (with external partners) but are not in user service. Also the neutron instrument E1 is currently being transferred to the Polish reactor MARIA.
“By this agreement we ensure, with the approval of the HZB Supervisory Board, that the neutron instruments of BER II will remain available to the user communities in Germany and Europe,” Prof. Dr. Anke Kaysser-Pyzalla, scientific director of HZB. The research reactor MARIA is currently undertaking extensive upgrades to a state-of-the-art facility, making it a highly attractive neutron source in Europe. The European and in particular the German user community will benefit from the re-location of the four neutron instruments from BER II. Once fully operational, the instruments will offer new research opportunities at the research reactor MARIA to all neutron users. A user service for scientists currently being set up.
The National Centre for Nuclear Research is the one of the largest research centers in Poland, with approximately 1,000 employees. It is home to the sole research nuclear reactor in the country. The research focus of NCBJ is on basic and applied research in widely understood nuclear physics, plasma physics, solid-state research and technological advancement. NCBJ also produces linear accelerators and radio isotopes for industry and medicine. More about NCBJ

- BESSY II: Phosphorous chains – a 1D material with 1D electronic propertiesFor the first time, a team at BESSY II has succeeded in demonstrating the one-dimensional electronic properties of a material through a highly refined experimental process. The samples consisted of short chains of phosphorus atoms that self-organise at specific angles on a silver substrate. Through sophisticated analysis, the team was able to disentangle the contributions of these differently aligned chains. This revealed that the electronic properties of each chain are indeed one-dimensional. Calculations predict an exciting phase transition to be expected as soon as these chains are more closely packed. While material consisting of individual chains with longer distances is semiconducting, a very dense chain structure would be metallic.
- Did marine life in the palaeocene use a compass?Some ancient marine organisms produced mysterious magnetic particles of unusually large size, which can now be found as fossils in marine sediments. An international team has succeeded in mapping the magnetic domains on one of such ‘giant magnetofossils’ using a sophisticated method at the Diamond X-ray source. Their analysis shows that these particles could have allowed these organisms to sense tiny variations in both the direction and intensity of the Earth’s magnetic field, enabling them to geolocate themselves and navigate across the ocean. The method offers a powerful tool for magnetically testing whether putative biological iron oxide particles in Mars samples have a biogenic origin.
- What vibrating molecules might reveal about cell biologyInfrared vibrational spectroscopy at BESSY II can be used to create high-resolution maps of molecules inside live cells and cell organelles in native aqueous environment, according to a new study by a team from HZB and Humboldt University in Berlin. Nano-IR spectroscopy with s-SNOM at the IRIS beamline is now suitable for examining tiny biological samples in liquid medium in the nanometre range and generating infrared images of molecular vibrations with nanometre resolution. It is even possible to obtain 3D information. To test the method, the team grew fibroblasts on a highly transparent SiC membrane and examined them in vivo. This method will provide new insights into cell biology.
