1. ICFA Mini-Workshop on Start-to-End Simulations for X-Ray FELs DESY-Zeuthen

2. 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

3. Program is focussed on work done on benchmark-scenarios based on LCLS and TESLA XFEL design Thanks to program committee Jean-Paul Carneiro Paul Emma Torsten Limberg Heinz-Dieter Nuhn - and to participants! TTF2 FEL, the VUV FEL at the TESLA Test Facility will play a poineering role

4. 1 GeV – 6 nm Norm. emittance: 2 mrad mm FWHM FEL pulse length: ca. 100 fs Peak current 2500 A Linac rep. rate 10 Hz Max. pulse rate 72 000 TTF2FEL Schedule: 2003 2004 2005 2006 2007 2008 Linac commissioning Injector installation Injector commissioning Complete vacuum installation Beam through undulator First Lasing @ 30 nm Saturation @30 nm First users @ 30 nm Tuning 30 – 120 nm Full beam current Installation of seeding and 3rd Harm. RF system 6 nm
