Dancing BESSY-VSR
Paul Goslawski from Godehard Wüstefeld's team was the initiator of this project: Why not demonstrate in vivid form, what the future project BESSY-VSR is all about? With novel cavities to be introduced in synchrotron storage ring BESSY II, the new BESSY-VSR is supposed to compress some of the stored electron buckets. So it is possible to produce brilliant light pulses with variable length: short and long pulses in one ring. The user is able to choose what kind of pulse he needs for his experiment. But the team still has to solve some tricky problems.
Two short movies are now produced to show how BESSY-VSR works and what remains to be solved: The principle as well as the difficulties are now being performed with a dance!
To realize his project, Paul quickly found enthusiastic volunteers: 24 colleagues took part, among them two heads of institutes. Most of them danced in a circle (the storage ring) as "electron buckets", while the "cavities" provided some drive to the system. With the help of a few more colleagues, the shooting of the videos itself only took one afternoon, whereas Paul spent some weekends editing the final film.
But it was worth the effort! Now, the two short films are available in the HZB media centre and on youtube, both in german and english language. "They could even be of good use in presentations", Paul says. Because only motion pictures can illustrate complex physics in an easy way.
- Helmholtz Doctoral Award for Hanna TrzesniowskiDuring her doctoral studies at the Helmholtz Centre Berlin, Hanna Trzesniowski conducted research on nickel-based electrocatalysts for water splitting. Her work contributes to a deeper understanding of alkaline water electrolysis and paves the way for the development of more efficient and stable catalysts. On 8 July 2025, she received the Helmholtz Doctoral Prize, which honours the best and most original doctoral theses in the Helmholtz Association.
- Research up close! The Long Night of Science at HZBOn 28 June, it's that time again: the Long Night of Science will take place from 5 pm to midnight in Berlin and also in Adlershof! Come around and take a look behind the scenes of our exciting research.
- MAX IV and BESSY II initiate new collaboration to advance materials scienceSwedish national synchrotron laboratory MAX IV and Helmholtz-Zentrum Berlin (HZB) with BESSY II light source jointly announce the signing of a 5-year Cooperation Agreement. The new agreement establishes a framework to strengthen cooperation for operational and technological development in the highlighted fields of accelerator research and development, beamlines and optics, endstations and sample environments as well as digitalisation and data science.
