3 We have established a baseline "350 MJ" target with specs we can all live with.... Can meet needs for gain, fabrication, & injection L.J. Perkins (LLNL) 1D calculation based on initial NRL design: LASER:2.459 MJ YIELD:364.7 MJ GAIN:148.3 (laser has picket pulse) DT Vapor (.0002 g/cc) DT Ice (fuel) Foam/DT (ablator) mm radius CH seal coat 334  m 153  m 5  m 800 Ǻ 50/50 Au/Pd outer layer demonstrated: imprint reduction, fast DT fill High IR reflectivity 5  m CH coating demonstrated seal, should get RMS < 50 nm 100 mg/cc foam can make this dia,  Gas temp 17.3  K balances physics and ice RMS Surface temp 18.6  K below DT Triple Point, allows for warmup J.

4 Materials Issues  Data Base ( S. Sharafat, Wed AM)  Establish a common set of specifications for candidate FW materials  SiC  W  Opportunity for community input... what other specs/materials we need?  Tying Together Our FW Exposure Expt's (J. Blanchard, Wed AM)  Guide for future experiments/other facilities Materials properties will be on the HAPL web site

6 Considerations for a less expensive path to IFE

7 The Dream…A plentiful, safe, clean energy source A 100 ton (4200 Cu ft) COAL hopper runs a 1 GWe Power Plant for 10 min Same hopper filled with IFE targets: runs a 1 GWe Power Plant for 7 years

8 The best way to make your dream comes true… make sure there’s a market for it

9 The Path to develop Laser Fusion Energy (from April 2003 HAPL mtg) Phase II Validate science & technology Phase III Engineering Test Facility operating  2020  Full size laser: 2.4 MJ, 60 laser lines  Optimize targets for high yield  Develop materials and components.   MW net electricity  Resolve basic issues by 2028 Phase I: Basic fusion science & technology Ignition Physics Validation MJ target implosions Calibrated 3D simulations Target Design & Physics 2D/3D simulations 1-30 kJ laser-target expts Full Scale Components Power plant laser beamline Target fab/injection facility Power Plant design Scalable Technologies Krypton fluoride laser Diode pumped solid state laser Target fabrication & injection Final optics Chambers materials/design 5 yr

10 Missions for Phase III: 1) Efficient use of taxpayer dollars 2) Success Ignites Private Investment AER CG Convincing case this leads to an attractive, efficient power plant James Watt’s Steam Engine

11 Suggested goals for Phase III Target physics…demonstrate high gain –Validate codes, show path to energy gain All key components work together at rep-rate –Laser –Optics –target fab/injection/engagement –Chamber –Thermal management –Tritium handling Make a convincing path to needed efficiency, durability, and economics

12 Parameters that can efficiently meet Phase III goals Laser Energy sub MJ 500 kJ Smaller, as this is the largest cost driver Phase III Parameter Rangenominal Target Gain Demo physics, confidence can get high gain Rep-Rate (Hz) Prototypical level Fusion Power (MW) Thermal management, nuclear issues Test materials/components (availability) 30-75% 60% Demo durability, test components Tritium Breeding & Recovery (TBR) Demo technology, afford to run it!!!

13 Concept of testing materials & components with a Laser IFE system Test Object Wall: 5.5 m radius (150 MW fusion power, 70% output in neutrons, 60% availability ) Power Plant Level Chamber (large enough to last life of facility) Target Laser Beams (Ports arranged in 6 rings) Radius (m) Fusion Neutron Flux (MW/m 2 ) Displacements/atom (dpa) M/I

14 Laser Energy sub MJ 500 kJ Smaller, as this is the largest cost driver Phase III Parameter Rangenominal Rep-Rate (Hz) Prototypical level Fusion Power (MW) Thermal management What new areas do we need to look at? Target Gain Demo physics, confidence can get high gain Test materials/components (availability) 30-75% 60% Demo durability, test components Tritium Breeding & Recovery Demo technology, afford to run it!!! Credible lower laser energy target designs Breeding options, particularly with materials testing Utility of laser based fusion materials tester for IFE (and MFE)

15 Lowering the development cost will help us realize our goal of a plentiful, safe, clean energy source.
