Lasers Phase I Goals

1. Develop technologies that can meet fusion energy
   requirements for efficiency (gt 6), repetition
   rate (5-10 Hz), and durability (gt
   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.

Final Optic Phase I Goals

1. Meet laser induced damage threshold (LIDT)
   requirements of more than 5 Joules/cm2, 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.

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

Long term material issues are being resolved.

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.

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).

1. Started Construction of Gas Driven Target
   Injector
2. Demonstrated Concept of Separable Sabot
3. Determining needed properties of DT

Target Design Phase I Goals

1. Develop credible target designs, using 2D and 3D
   modeling, that have sufficient gain (gt 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.
