A phased program to develop Laser Fusion Energy Develop Viable:Scalable Laser Technologies Target designs Target fab/ inj Final optics Chamber Concept Phase I: Science and technology Start 1999 Establish:Target physics Full scale Laser technology Target Mass Production Injection/tracking in Chamber Final Optics Power Plant design Phase II Integrated Research Experiments and more start  2006  2-3 MJ, 60 laser beam lines  High gain target implosions  Optimize materials & components.   300 MW electricity (burst mode) Phase III Engineering Test Facility start  , operating  2022  Demonstrate useable electrical power from Fusion IFE DEMO POINT DESIGN for External Review

Lasers Phase I Goals 1.Develop technologies that can meet fusion energy requirements for efficiency (> 6%), repetition rate (5-10 Hz), and durability (> 100,000,000 shots continuous). 2.Demonstrate required laser beam quality and pulse shaping 3.Laser technologies employed must scale to reactor size laser modules and projected to have attractive costs for commercial fusion energy. KrF Laser (Electra-NRL) DPSSL (Mercury-LLNL)

Final Optic Phase I Goals 1.Meet laser induced damage threshold (LIDT) requirements of more than 5 Joules/cm 2, in large area optics. 2.Develop a credible final optics design that is resistant to degradation from neutrons, x-rays, gamma rays, debris, contamination, and energetic ions. stiff, lightweight, cooled, neutron transparent substrate 85° Laser UCSD

Chambers Phase I Goals 1.Develop a viable first wall concept for a fusion power plant. 2.Produce a viable “point design” for a fusion power plant UCSD Wisconsin SNL ORNL LLNL Long term material issues are being resolved. Example- Ion exposures on RHEPP

Target Fabrication Phase I Goals 1.Develop mass production methods to fabricate cryogenic DT targets that meet the requirements of the target design codes and chamber design. Includes characterization. 2.Combine these methods with established mass production costing models to show targets cost will be less than $0.25. Developed thin Au/Pd coatings with high DT permeability and IR reflectivity. Established chemistry for foam shells General Atomics Schafer Corp Targets $0.16 each from chemical process plant methodology General Atomics

Target Injection / Tracking Phase I Goals 1.Build an injector that accelerates targets to a velocity to traverse the chamber (~6.5 m) in 16 milliseconds or less. 2.Demonstrate target tracking with sufficient accuracy for a power plant (+/- 20 microns). Turbo Pumps Gun Barrel Target Catcher Target Position Detectors Sabot Deflector Revolver Chamber Expansion Tanks 1.Started Construction of Gas Driven Target Injector 2.Demonstrated Concept of Separable Sabot 3.Determining needed properties of DT General Atomics, LANL

Target Design Phase I Goals 1.Develop credible target designs, using 2D and 3D modeling, that have sufficient gain (> 100) + stability for fusion energy. 2.Benchmark underlying codes with experiments on Nike & Omega 3.Integrate design into needs of target fab, injection and reactor chamber.
