Hydrodynamic instability experiments with three-dimensional modulations at the National Ignition Facility

Three-dimensional HYDRA simulations of National Ignition Facility targets*

The performance of a targets designed for the National Ignition Facility ~NIF! are simulated in three dimensions using the HYDRA multiphysics radiation hydrodynamics code. @M. Marinak et al., Phys. Plasmas 5, 1125 ~1998!# In simulations of a cylindrical NIF hohlraum that include an imploding capsule, all relevant hohlraum features and the detailed laser illumination pattern, the motion of the w...

Modeling of multi-interface, diverging, hydrodynamic experiments for the National Ignition Facility

The National Ignition Facility (NIF) will soon provide experiments with far more than ten times the energy than has been previously available on laser facilities. In the context of supernova-relevant hydrodynamics, this will enable experiments in which hydrodynamic instabilities develop from multiple, coupled interfaces in a diverging explosion. This paper discusses the design of such blast-wav...

Advanced Gated X-Ray Imagers for Experiments at the National Ignition Facility

X-ray imaging is integral to the measurement of the properties of hot plasmas. To this end, a suite of gated x-ray imagers have been developed for use in a wide range of experiments at the National Ignition Facility (NIF). These instruments are sensitive to x-rays over the range of 0.7-90keV and can acquire images at 20ps intervals for source intensities ranging over several orders of magnitude...

Relativistic Plasma Physics at the National Ignition Facility

Neutron activation diagnostics at the National Ignition Facility (invited).

Neutron yields are measured at the National Ignition Facility (NIF) by an extensive suite of neutron activation diagnostics. Neutrons interact with materials whose reaction cross sections threshold just below the fusion neutron production energy, providing an accurate measure of primary unscattered neutrons without contribution from lower-energy scattered neutrons. Indium samples are mounted on...
