Energy and Technology Review
- eds.
The Lawrence Livermore National Laboratory, was established in 1952 to do research on nuclear weapons and magnetic fusion energy. Since then, we have added other major programs, including laser fusion and laser isotope separation, biomedical and environmental science, strategic defense, and applied energy technology. These programs, in turn, require research in basic scientific disciplines, including chemistry and materials science, computer science and technology, engineering, and physics. The Laboratory also carries out a variety of projects for other Federal agencies, Energy and Technology Review is published monthly to report on unclassified work in all our program. Three projects are described in this issue. Numerical simulations of electromagnetic waves and plasmas in realistic geometries. Our numerical methods for simulating electromagnetic waves and plasmas in realistic geometries allow the use of unstructured meshes. Simulations can now address the spatial scales and boundary shapes of real devices, making them more useful for engineering applications that range from accelerators and fusion reactor components, to plasma torches, electronic devices, antenna design, and radar cross sections. Kestrel: A high-altitude balloon platform. We have design and tested a ship-board, balloon-launch method for flying a scientific payload at altitudes above 25 km for a period of several hours to obtain missile-launch plume data at infrared, visible, and ultraviolet wavelengths. Increasing laser power with beamlet architecture. We are developing a new laser architecture to increase the power output of lasers used for inertial confinement fusion experiments. This architecture is an assembly of optically independent units or modules called ``beamlets.`` Each beamlet will have an aperture of about 30 cm{sup 2} and will deliver to the target an output of 3.5 to 7.0 kJ at a 351-nm wavelength.
