Measurements demonstrate that
required adjustments are achievable
• Minimum timing adjustment: ± 50 ps
• Minimum amplitude adjustment: ± 3%
Shock timing and amplitude will be
adjusted for implosion efficiency

37
High-energy high-intensity missions define thelaser requirements
38
Conceptual full scale proton fast ignition mustsatisfy many criteria - design is evolving
39
High energy petawatts require beamlinemodification
40
The petawatt beam in the target bay will beeasily switched from the long-pulse beam path
41
NIF could be adapted for full scale high gain FI
