HED Science Research at LLNL

High Energy Density science is the study of matter and energy under extreme conditions, such as condensed matter at densities found in the core of giant planets or hot plasmas typical of stellar interiors.

This work integrates multiple disciplines, including atomic, nuclear, and condensed-matter physics. It also involves efforts to generate HED conditions in the laboratory, creating a microphysics observatory to study the HED domain, and enabling scientists to manipulate matter and energy toward achieving controlled fusion. In addition, they leverage LLNL’s powerful predictive modeling and simulation capabilities to explore the complex behavior of HED matter, and they develop and enhance diagnostic tools that support HED science research.
