20. Risk Assessment - Technical
Accelerator
SASE theory validated by experiments
Computation/simulation tools highly developed, agree with experiments
Slice emittance at undulator is a key measure of technical risk
Project goal 1.2 mm-mrad normalized emittance at the undulator entrance
Saturation at 8 keV achieved for 1.5 mm-mrad, with 122 meter undulator channel
Saturation at 8 keV achieved for 1.9 mm-mrad with 150 meter undulator channel
Ample safety factor for saturation at 0.8 keV
Undulator
Prototype in hand
Peak field goal exceeded
Chamber prototyping

X-ray Endstation Systems
Routine technical risks
LCLS DOE Review, April 23, 2002
