European XFEL

@europeanxfel.bsky.social

An international research facility that generates extremely intense X-ray flashes used by researchers from all over the world. Learn more on www.xfel.eu

No camera (or detector) can capture two images only femtoseconds apart. Scientists now present methods to disentangle double exposures to reveal before-and-after images of nanoparticles. 🧪⚛️ (Illustration: ETH Zurich)

Advance your postdoctoral career in ultrafast science, photon science and large-scale research facilities. LEAPS ULTRAFAST offers postdoctoral researchers the opportunity to carry out their research projects within a European network of leading research infrastructures. Details: leaps-ultrafast.eu

The European LEAPS ULTRAFAST Postdoctoral Network accepts applications from early-career researchers in ultrafast science until 30 September 2026. Coordinated by DESY and funded by the European Union, the programme connects leading research infrastructures across Europe that are members of LEAPS, i.e., the "League of European Accelerator-based Photon Sources". LEAPS ULTRAFAST offers outstanding research opportunities, structured training and international networking across leading European research environments.  
We welcome applications from excellent postdoctoral researchers with innovative project ideas. Please consult the website for eligibility criteria, host options and appointment conditions.
Deadline: 30 September 2026

LEAPS ULTRAFAST promotes excellence in European ultra-short-time research
LEAPS ULTRAFAST brings together leading synchrotron and free-electron laser facilities as well as major photon-science research centres across Europe. The programme aims to connect outstanding postdoctoral researchers with world-class science, advanced technologies and a strong international research network.
Funded by the European Commission through the Marie Skłodowska-Curie Actions (MSCA COFUND) programme and coordinated by DESY, LEAPS ULTRAFAST will offer around 50 postdoctoral fellowships across six European countries over the next five years. Research topics range from ultrafast dynamics in matter and quantum technologies to energy research, health sciences and advanced imaging methods.
Researchers, students and members of the international scientific community are warmly invited to discover the opportunities offered by the LEAPS ULTRAFAST Postdoctoral Network.

European XFEL takes a stand for diversity

Research institution makes a visible statement in support of diversity, solidarity and open-mindedness
 
As part of Hamburg Pride Week, taking place from 24 July to 3 August 2026, European XFEL is joining the “Hamburg zeigt Flagge” initiative alongside more than 400 other organisations displaying rainbow flags in this period. In doing so, the research institution is reaffirming its strong commitment to diversity as a key element of an inclusive working environment.

For the first time this year, a group of European XFEL employees will also jointly visit the Christopher Street Day parade on 1 August in the Hamburg city centre. This year’s event is held under the motto: “Queer solidarity. Taking a stand – for a future without fear!”

Managing Director Nicole Elleuche says: “Our support of Pride Week reflects our conviction that diversity strengthens research, collaboration and the way we live together as a society. We want to take a clear stand and help shape a future in which people can live free from fear and discrimination.”

Ryszard Sobierajski takes over as Chairman of the European XFEL Council, Karel Saksl becomes Vice Chairman European XFEL thanks outgoing Chairman Federico Boscherini. Thomas Feurer, Chairman of the Management Board of European XFEL, congratulated both Sobierajski and Saksl.

European XFEL further expands its support for PhD students Students’ Day offers insights into projects 🧪🔬⚛️  More structure, more exchange, even better results: European XFEL is strengthening PhD training.

X-ray imaging at a facility such as the European XFEL has little in common with medical X-rays produced in a doctor's office. However, scientific X-ray imaging also makes the invisible visible, albeit by using different physical principles. ⚛️🧪

What makes X-rays powerful enough to reveal structures down to the nanoscale? ⚡🔬 This article takes students into the world of cutting-edge research at the European XFEL @europeanxfel.bsky.social. Read here: scienceinschool.org/article/2026... #EduSky

Many experiments conducted at European XFEL, such as measurements related to #fusion energy at our HED-HIBEF instrument, require computer simulations to produce meaningful results. ⚛️🧪 Accelerating these simulations by a factor of 50 is huge!

Understanding extreme states of matter faster: Researchers at #HZDR have developed a new procedure, enabling them to speed up computer simulations that analyze matter under extreme conditions. @europeanxfel.bsky.social #fusion #X-ray #scattering #astrophysics #HIBEF ▶️ www.hzdr.de/presse/tddft_xrts

Target chamber at the High Energy Density instrument at the European XFEL, where two optical lasers operated by the HIBEF consortium enable the creation of extreme states of matter. The new computational method provides the simulations required for temperature and density diagnostics.

Diversity is like a varied #buffet. To celebrate German #Diversity Day 2026 (DDT26), staff from European XFEL came together to eat and chat. The highlighe buffet consisted of traditional dishes that the staff had brought along. Six hundred people from more than 60 countries work at EuXFEL.

Diversity is like a varied buffet. To celebrate German Diversity Day 2026 (DDT26), staff from European XFEL came together to eat and chat. Six hundred people from more than 60 countries work on the world’s largest X-ray research laser – not counting the rotating international research teams who travel from all over the world to the Campus to conduct experiments.

Next generation ahead! Girls’ and Boys’ Day at European XFEL Young people look behind the scenes of the research facility 🧪🔬⚛️ On 23 April, European XFEL welcomed 60 school pupils for insights into the world of research as part of the nationwide Girls’ and Boys’ Day.
