Hydrodynamic Aspects of the Split-Foil Laser Target Design( Book )

2 editions published in 1986 in English and held by 2 WorldCat member libraries worldwide

Hydrodynamic simulations of exploding copper foils, which are irradiated on one side by 1.06 micron laser light, indicated that peak axial electron number density is more easily controlled with split-foil target design. Results from a series of simulations with solid copper foils that range in width from 500A to 1500A show that while peak electron temperature and time of burnthrough can be varied, evolved electron number densities are approximately bounded from above by 3 X 10 to the 20th power particles/cc. By increasing foil thickness to 1 micron and introducing aa slit on the foil axis of 100 micron width, uniform plasmas with electron number densities on the order of 6 X 10 to the 20th power particles/cc can be generated. Essentially the same results are obtained from simulations with split selenium foils. Keywords: X-ray lasers, Laser-matter interactions, Hydrodynamic simulation
The Rayleigh-Taylor Instability in Ablatively Accelerated Targets with 1, 1/2 and 1/4 Micrometers Laser Light( Book )

1 edition published in 1987 in English and held by 1 WorldCat member library worldwide

The results of a series of detailed numerical simulations are presented for the Rayleigh-Taylor instability in laser ablatively accelerated targets for a fairly wide range of initial conditions. It is shown that the Rayleigh-Taylor growth rate in an ablative environment is a strong function of the laser wavelength. For perturbation wavelengths about 3 times the inflight target thickness, the ratios of the numerical growth rates to the classical growth rates are of the order of 1/1.5, 1/2.5 and 1/3.5 for 1, 1/2 and 1/4 micrometer laser light respectively. The numerical results are in good agreement with out theoretical based on the ablative convection of vorticity away from the unstable ablation front. These results provide strong evidence for the viability of high aspect ratio shells in direct drive laser fusion. Keywords: Laser ablation; Inertial confinement fusion; Hydrodynamic instabilities
Proceedings of the Workshop on Power Sources for Distributed Autonomous Systems( )

1 edition published in 2005 in English and held by 0 WorldCat member libraries worldwide

The Workshop on Power Sources for Distributed Autonomous Systems was held on 23-24 February 2004 at the Naval Research Laboratory in Washington, DC. The purpose was to explore optimization, utilization, and integration of power and energy sources to enable new and high-value DoD distributed autonomous systems capabilities. Four central consensus conclusions emerged. The realization of future and high-value Department of Defense (DoD) distributed autonomous systems capabilities will require significant focus on power integration. All components of autonomous systems, including power and energy sources, should be considered at design inception and carried through fruition in a concerted effort. Current availability of capable miniature/low-power sensors, communications hardware, data storage and processing tools, platform mobility elements, energy and power awareness, and R & D-oriented systems design provides an expeditious opportunity to achieve new and useful distributed autonomous systems capabilities. Highest likelihood for success is by means of enfranchising multiple small, applications driven, interdisciplinary development teams of scientists, engineers and DoD customers
Naval Research Laboratory Space Science Division Newsletter: 01/2007( )

1 edition published in 2007 in English and held by 0 WorldCat member libraries worldwide

The Naval Research Laboratory (NRL) Space Science Division (SSD) conducts a broad-spectrum RDT & E program in solar-terrestrial physics, astrophysics, upper/middle atmospheric science, and astronomy. Instruments to be flown on satellites, sounding rockets and balloons, and ground-based facilities and mathematical models are conceived and developed. Division researchers apply these and other capabilities to the study of the atmospheres of the Sun and the Earth, including solar activity and its effects on the Earth's ionosphere, upper atmosphere and middle atmosphere, laboratory astrophysics, and the unique physics and properties of celestial sources. The program is important to orbital tracking, radio communications and navigation that affect the operation of ships and aircraft, utilization of the near-space and space environment of the Earth, and to the fundamental understanding of natural radiation and geophysical phenomena. This first quarterly newsletter provides highlights of SSD activities in January 2007, and a summary of SSD accomplishments in 2006
