The Helmholtz-Zentrum Berlin (HZB) will intensify its cooperation with Jordanian large-scale research facilities. This was agreed between Prof. Dr. Jan Lüning and representatives of a high-ranking Jordanian research delegation, which visited the HZB at the end of November 2018.
On 27 November 2018, H.E. Dr. Khaled Toukan, Chairman of the Jordanian Atomic Energy Commission and Director of the synchrotron radiation source SESAME, and Dr. Samer Kahook, Manager of the Jordanian Research and Training Reactor JRTR, visited the HZB. They were accompanied by Akram Hayajneh, 2nd Secretary of the Jordanian Embassy in Berlin.
The delegation was informed about the science, the user service and the operation of the neutron source BER II at the Lise-Meitner-Campus. Afterwards, the designated scientific director of the HZB, Prof. Dr. Jan Lüning, led them through the BESSY II experimental hall in Adlershof. In discussions, the delegation talked with representatives from the HZB about the perspectives of Jordan's large-scale research facilities. Another topic was possible support for the Jordanian research reactor against the background of the final shutdown of the BER II at the end of 2019.
HZB has been engaged in SESAME for many years
In addition, the long-standing cooperation between SESAME and HZB was to be further expanded, said the delegates. The synchrotron radiation source SESAME works with the electron accelerator of BESSY I. After decommissioning of that facility, the components were transferred to Jordan in 2002 and successfully installed in SESAME with the help of experts from Germany and other European countries. These components still run very reliably today, emphasized SESAME Director Dr. Khaled Toukan.
Training opportunities for Jordanian scientists
During the meeting, both sides agreed that there would be further training opportunities for Jordanian scientists at BESSY II.
The HZB is also involved in setting up a new beamline for soft X-ray light at SESAME. As reported, the Helmholtz Association will provide 3.5 million euros for this project. The HZB will build an APPLE II undulator for the new SESAME beamline, train the Jordanian team and support them with remote maintenance.
- A simpler way to inorganic perovskite solar cellsInorganic perovskite solar cells made of CsPbI3 are stable over the long term and achieve good efficiencies. A team led by Prof. Antonio Abate has now analysed surfaces and interfaces of CsPbI3 films, produced under different conditions, at BESSY II. The results show that annealing in ambient air does not have an adverse effect on the optoelectronic properties of the semiconductor film, but actually results in fewer defects. This could further simplify the mass production of inorganic perovskite solar cells.
- Spintronics: A new path to room temperature swirling spin texturesA team at HZB has investigated a new, simple method at BESSY II that can be used to create stable radial magnetic vortices in magnetic thin films.
- BESSY II: How pulsed charging enhances the service time of batteriesAn improved charging protocol might help lithium-ion batteries to last much longer. Charging with a high-frequency pulsed current reduces ageing effects, an international team demonstrated. The study was led by Philipp Adelhelm (HZB and Humboldt University) in collaboration with teams from the Technical University of Berlin and Aalborg University in Denmark. Experiments at the X-ray source BESSY II were particularly revealing.
