Properties of Materials under Extreme Conditions and Hydrodynamics
Research proposals are solicited in the area of fundamental properties and response of materials under extreme conditions and hydrodynamics. The specific sub-areas of interest are:

• Investigations of the static and dynamic (i.e., shock-compressed) properties of materials under conditions of high-pressure, high-temperature (1-10 eV regime), high-strain and high-strain-rate. Materials properties of interest include thermodynamic properties (equation-of-state, high-pressure phase diagram, pressure-induced phase transformation, etc.) and mechanical constitutive properties (plasticity and strength, failure, fracture, etc.);
• Hydrodynamic experiments in low-energy-density physics regimes where materials properties (strength, etc.) dominate; and
• Development of novel advanced diagnostics and measurement techniques leading to (1) the observation of physical phenomena at appropriate length and time scales with particular emphasis on in situ techniques and (2) development and experimental validation of physics-based multi-scale models of the dynamic response of materials.

High-Energy-Density Physics
Research proposals are solicited in the area of high-energy-density physics and fluid dynamics, with particular emphasis on experimental investigations based on the utilization of lasers and/or pulsed power technology. The specific sub-areas of interest are:

• Investigation of the properties of matter in high-energy-density regimes, e.g. as produced by lasers and/or pulsed power. This includes investigations in related areas of hydrodynamics, plasma physics, properties of materials under high-energy-density conditions, inertial fusion, atomic physics, radiation generation, and the interaction of radiation with matter;
• Investigation of the physics associated with astrophysical phenomena that may be done using NNSA's facilities; NIF, Omega, or Z.
• Physics of turbulence and fluid interfaces; and
• Development of novel diagnostics and measurement techniques for the observation of physical phenomena under high energy density conditions.

Low-Energy Nuclear Science
Research proposals are solicited in the area of nuclear science with an emphasis on low energies. The specific sub-areas of interest are:

• Investigations leading to greater accuracy in the knowledge of low energy cross sections of stable and unstable nuclei and corresponding reaction rates for neutron-, g- and ion-induced reactions for both simulation and radiochemistry diagnosis;
• Development of advanced simulations and measurement techniques leading to improved radiation and particle detection methods, in terms of energy and spatial resolution;
• Physics of the fission process, including division of mass and charge as a function of excitation, production of energy, and the reaction properties of prompt fission products;
• Investigations of particle production and advanced diagnostic techniques relevant to high-energy proton radiography and advanced diagnostic techniques relevant to X-ray radiography; and
• Development of experimental diagnostic techniques for laser or pulsed power implosion systems.
