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

- Ultrafast demagnetisation - Thinner iron, stronger effectThe thinner an iron film, the more easily it can be demagnetised by a laser pulse. Researchers at the University of Duisburg-Essen, working with Helmholtz-Zentrum Berlin and other partners, have discovered why: the key lies in the magnetic order at the material's interfaces. In the long term, these findings could contribute to the development of new technologies for magnetic data storage. The results have been published in the scientific journal Advanced Science.
- Blind spot for the arrangement of atomsArtificial intelligence is increasingly being used to predict the properties of new materials. A research team from Jena and the United States now shows in a study published in the journal Nature Computational Science that when language models are used for this purpose, they reliably identify which types of atoms a material contains. However, they make insufficient use of information about how those atoms are arranged in space. Neither larger models nor additional training data resolve this weakness. For material properties that depend strongly on structure, AI models specifically designed to process spatial relationships are therefore the more reliable choice. (DOI: 10.1038/s43588-026-01045-2)
- Patterns of polar vortices in lead-free superlattices on siliconA team at HZB has, for the first time, reported polar vortices in (BaTiO3/SrTiO3)10 superlattices on silicon. These results expand the range of materials and substrates on which polar topological textures can occur and open up new options for incorporating complex ferroelectric states into silicon-based technologies.
