Target Technologies

Conclusion: An inertial fusion energy program would require expanded effort on target fabrication, injection, tracking, survivability, and recycling. Target technologies developed in the laboratory would need to be demonstrated on industrial mass production equipment. A target technology program would be required for all promising inertial fusion energy options, consistent with budgetary constraints. (Conclusion 3-9)

Chamber Technologies

Conclusion: The chamber and blanket are critical elements of an inertial fusion energy power plant, providing the means to convert the energy released in fusion reactions into useful applications as well as the means to breed the tritium fuel. The choice and design of chamber technologies are strongly coupled to the choice and design of driver and target technologies. A coordinated development program is needed. (Conclusion 3-10)

The National Ignition Facility

Conclusion: The National Ignition Facility, designed for stockpile stewardship applications, is also of great potential importance for advancing the technical basis for inertial fusion energy research. (Conclusion 4-15)

Conclusion: There has been good technical progress during the past year in the ignition campaign carried out on the National Ignition Facility. Nevertheless, ignition has been more difficult than anticipated and was not achieved in the National Ignition Campaign, which ended on September 30, 2012. The results of experiments to date are not fully understood. It will likely take significantly more than a year to gain a full understanding of the discrepancies between theory and experiment and to make modifications needed to optimize target performance. (Conclusion 2-1)

Recommendation: The target physics programs on the NIF, Nike, OMEGA, and Z should receive continued high priority. The program on NIF should be expanded to include direct drive and alternative modes of ignition. It should aim for ignition with moderate gain and comprehensive scientific understanding, leading to codes with predictive capabilities for a broad range of IFE targets. (Recommendation 2-1)
