The NIF, the world's most energetic laser has been operational since 2009, and is now transitioning to an international user facility for high-energy-density and inertial fusion research. This paper summarizes NIF's experimental capabilities and results.
Although most laboratory plasmas are produced from heating of solids, little is known about the properties of the intervening states during evolution of a cold solid into hot plasma. Such states lie in the so-called Warm Dense Matter regime where temperature is comparable to Fermi energy and density is sufficiently high to render the ions strongly coupled. Experimental studies of Warm Dense Matter...
Experimental results are presented on the properties of a custom-designed fast-response lithium-6 glass scintillator for inertial confinement fusion diagnostics. This newly developed scintillator promises as an indispensable tool in the realization of scattered neutron diagnostics.
Recently ultra fast diagnostic techniques have been developed to investigate imploded core plasma of shell-cone target for fast ignition in laser fusion research. One and two dimensional X-ray image sampling and two dimensional image reconstruction techniques have been applied to X-ray streak cameras. Multi-imaging X-ray streak (MIXS) camera, sampling image X-ray streak camera and multichannels MIXS...
Integrated experiments of fast ignition for FIREX-1 project have been performed with Gekko-XII and LFEX lasers at the Institute of Laser Engineering, Osaka University. Implosion and heating dynamics have been intensively studied.
Summary form only given. Los Alamos National Laboratory (LANL) has a diverse and cutting-edge experimental research program using short-pulse lasers. This program applies state of the art technologies in modeling and supercomputing, material science and target fabrication, diagnostics and experimental techniques, laser science, and laser facilities ranging from the small to the large scale. Some of...
The development of a hot-hohlraum platform to facilitate the experimental study of matter in extreme states is important for future high-energy density physics (HEDP) at the National Ignition facility (NIF). Specifically, HEDP experiments can be used to test the accuracy of current models and databases for the equation of state (EOS) and X-ray opacity of materials. In the past, both laser and Z-pinch...
The growth of a radially symmetric ripple superimposed on a single intense Gaussian laser beam in a collisionless magnetized plasma is investigated. WKB and Paraxial ray approximations are used to calculate wave equation for the main beam and the ripple. Numerical results show that the relativistic power of laser beam, the dynamics of ripple gets affected by its position and phase angle as well as...
