• X-ray FELs will be the first multi-million accelerator projects with key performance depending exponentially on beam quality.

• New beam parameter regime & effects

Reliable understanding of beam dynamics of paramount importance

Power gain length

Program is focussed on work done on benchmark-scenarios based on LCLS and TESLA XFEL design

- and to participants!

TTF2 FEL, the VUV FEL at the TESLA Test Facility will play a poineering role
