This year marks a remarkable milestone: the 25th anniversary of the first lasing at the TESLA Test Facility (TTF) – today known as FLASH. This breakthrough laid the foundation for the worldwide development of outstanding free-electron laser (FEL) user facilities.
To mark this pioneering achievement, a two-day international scientific symposium on 17–18 November 2025 will take place at DESY in Hamburg.
The programme will include historical retrospectives, reviews of major technological advances, scientific highlights, a dedicated PhD session, and ample opportunities to meet and reconnect with colleagues and companions.
