Temporally Coherent Synchrotron Light Sources

A satellite event to the 2026 DESY/XFEL Photon Science Users' Meeting

 

With this workshop we aim to connect the photon science, storage ring, and FEL communities to explore advanced capabilities of state-of-the-art facilities and identify a path towards the next generation accelerator-based radiation sources. Recent advances in seeded FELs and FEL oscillators, as well as controlled and stable-state microbunching in storage rings, indicate a high potential of further improving longitudinal coherence in both linac-driven and ring-based sources and exploiting synergies between them. The workshop will have four tracks:

• Advanced coherent generation schemes
• Experimental techniques and science cases
• Transverse and longitudinal coherence properties of undulator radiation
• Intensity limitations and beam control

 

The workshop is being held as a satellite event to the 2026 DESY/XFEL Photon Science Users' Meeting. Link to the meeting agenda.
