Improved Single Bunch Purity
Operational News -
Operational News - Based on the ongoing commissioning work, we are now able to offer a much improved purity for single bunch operation. The purity has improved by more than one order of magnitude (>10^4), being independant of beam current and life time of the fill. The bunch purity gives the ratio of electrons concentrated in one bunch to electrons in other locations in the storage ring. The better the purity, the better the experimental conditions for researchers involved in time-resolved studies.

- SEAlab accelerator project completed: Achievements and outlookThe SEAlab accelerator project successfully completed its final measurement campaign in summer 2026. The facility is now being dismantled, with many components set to be reused. The two accelerator physicists, Axel Neumann and Thorsten Kamps, explain what the project has achieved and provide an outlook for the future.
- Kick-off for a new data and AI centre in BerlinBy establishing a new data and AI centre in Berlin, the Zuse Institute Berlin (ZIB) and the Helmholtz-Zentrum Berlin (HZB) are laying the foundations for a scalable and sovereign data infrastructure in the capital. The project strengthens the scientific capabilities of Berlin’s research community whilst making an important contribution to research security, resilience and technological independence.
