NIAC2026¶
The NIAC2026 meeting will be held as a hybrid event hosted by the European X-ray Free-Electron Laser (European XFEL) & the Deutsches Elektronen-Synchrotron (DESY), in the Hamburg area - Germany from 25th to 27th September 2026, the weekend after/adjacent to the 2026 NOBUGS conference.
People will be able to participate both onsite and online (via Zoom). In order to better overlap with other time zones, the meeting sessions will be shorter and later in the day (CEST) over 3 days. The meeting programme on Friday September 25 will contain three public sessions.
Venue and Accommodation¶
The 3.4 km long European X-ray Free-Electron Laser generates extremely intense X-ray flashes used by researchers from all over the world at seven scientific instruments to map atomic details of viruses, film chemical reactions, and study processes in the interior of planets.
DESY is one of the world’s leading centres for research on and with particle accelerators, operating PETRA-III, one of the brightest storage ring X-ray radiation sources in the world, and the Free-Electron Laser facility FLASH.
The NIAC2026 meeting will take place on the DESY campus.
