HEDLP FESAC Subpanel Web Site
The Department of Energy Under Secretary for Science Dr. R. L. Orbach and the Under Secretary for Nuclear Security Mr. T. P. D'Agostino have charged the Fusion Energy Science Advisory Committee (FESAC) to "work with the HEDLP (High Energy-Density Laboratory Plasmas) community to provide information to develop "a scientific roadmap for the joint HEDLP program in the next decade."
A FESAC subpanel has been formed to address the charge. The charge letter requires that FESAC identifies: (1) "the compelling scientific opportunities for research in fundamental HEDLP that could be investigated using existing and planned facilities in support of the OFES and NNSA/DP missions; (2) the scientific issues of implosion and target design that need to be addressed to make the case for inertial fusion energy as a potential future energy source."
To stimulate feedback from the community, the HEDLP panel has developed a PRELIMINARY classification in themes and categories of the HEDLP program to address the charge. Such a classification is subject to changes as the committee gathers community input.
High energy-density laboratory plasma physics themes:
- Fundamental science within the HEDLP framework
- High energy-density physics for inertial fusion energy
Theme (1) is divided into two categories:
- Properties of matter at high energy density
- Broad-scope science with HEDLP facilities
Category (a) includes all the scientific issues pertaining to the properties and dynamics of matter at high energy densities. Category (b) includes broad scope scientific issues that can be addressed using the tools and facilities of HEDLP such as high energy lasers, high power lasers, x-ray lasers, pulsed power, particle accelerators and others. These scientific issues may or may not pertain to matter in the high energy-density regime.
Theme (2) is also divided into two categories:
- Compression and heating of high energy-density fusion plasmas
- Concept optimization for inertial fusion energy
Category (a) includes the high energy-density science related to the generation and understanding of HED fusion plasmas such as driver coupling, implosion stability and thermonuclear gain. Scientific issues pertaining to the generation mechanisms and diagnostic tools are also included even if not necessarily in the high energy-density regime. Category (b) pertains to the scientific issues related to the different approaches to achieving IFE. It also includes optimized target designs, driver efficiencies and science issues related to other practical aspects of IFE.Charge letter
