Benchmark Measurements of the Ionization Balance of Non-LTE Gold (open access)

Benchmark Measurements of the Ionization Balance of Non-LTE Gold

The authors present a series of benchmark measurements of the ionization balance of well characterized gold plasmas with and without external radiation fields at electron densities near 10{sup 21} cm{sup -3} and various electron temperatures spanning the range 0.8 to 2.4 keV. They have analyzed time- and space-resolved M-shell gold emission spectra using a sophisticated collisional-radiative model with hybrid level structure, finding average ion changes <Z> ranging from 42 to 50. At the lower temperatures, the spectra exhibit significant sensitivity to external radiation fields and include emission features from complex N-shell ions not previously studied at these densities. The measured spectra and inferred <Z> provide a stringent test for non-local thermodynamic equilibrium (non-LTE) models of complex high-Z ions.

Commercial Aviation: Potential Safety and Capacity Issues Associated with the Introduction of the New A380 Aircraft (open access)

Commercial Aviation: Potential Safety and Capacity Issues Associated with the Introduction of the New A380 Aircraft

A letter report issued by the Government Accountability Office with an abstract that begins "Airbus S.A.S. (Airbus), a European aircraft manufacturer, is introducing a new aircraft designated as the A380, which is expected to enter service in late 2007. The A380 will be the largest passenger aircraft in the world, with a wingspan of about 262 feet, a tail fin reaching 80 feet high, and a maximum takeoff weight of 1.2 million pounds. The A380 has a double deck and could seat up to 853 passengers. GAO was asked to examine the impact of the A380 on U.S. airports. In May 2006, GAO issued a report that estimated the costs of infrastructure changes at U.S. airports to accommodate the A380. This report discusses (1) the safety issues associated with introducing the A380 at U.S. airports, (2) the potential impact of A380 operations on the capacity of U.S. airports, and (3) how selected foreign airports are preparing to accommodate the A380. To address these issues, GAO reviewed studies on operational and safety issues related to the A380 and conducted site visits to the 18 U.S. airports and 11 Asian, Canadian, and European airports preparing to receive the A380. GAO provided the …

Continuation of the Application of Parallel PIC Simulations to Laser and Electron Transport Through Plasmas Under Conditions Relevant to ICF and SBSS (open access)

Continuation of the Application of Parallel PIC Simulations to Laser and Electron Transport Through Plasmas Under Conditions Relevant to ICF and SBSS

One of the important research questions in high energy density science (HEDS) is how intense laser and electron beams penetrate into and interact with matter. At high beam intensities the self-fields of the laser and particle beams can fully ionize matter so that beam -matter interactions become beam-plasma interactions. These interactions involve a disparity of length and time scales, and they involve interactions between particles, between particles and waves, and between waves and waves. In a plasma what happens in one region can significantly impact another because the particles are free to move and many types of waves can be excited. Therefore, simulating these interactions requires tools that include wave particle interactions and that include wave nonlinearities. One methodology for studying such interactions is particle-in-cell (PIC) simulations. While PIC codes include most of the relevant physics they are also the most computer intensive. However, with the development of sophisticated software and the use of massively parallel computers, PIC codes can now be used to accurately study a wide range of problems in HEDS. The research in this project involved building, maintaining, and using the UCLA parallel computing infrastructure. This infrastructure includes the codes OSIRIS and UPIC which have been improved …

The Energy Diameter Effect (open access)

The Energy Diameter Effect

Various relations for the detonation energy and velocity as they relate to the inverse radius of the cylinder are explored. The detonation rate-inverse slope relation seen in reactive flow models can be used to derive the familiar Eyring equation. Generalized inverse radii can be shown to fit large quantities of cylinder and sphere results. A rough relation between detonation energy and detonation velocity is found from collected JWL values. Cylinder test data for ammonium nitrate mixes down to 6.35 mm radii are presented, and a size energy effect is shown to exist in the Cylinder test data. The relation that detonation energy is roughly proportional to the square of the detonation velocity is shown by data and calculation.

Geothermal Direct Use Feasibility Study on the Fort Bidwell Indian Reservation (open access)

Geothermal Direct Use Feasibility Study on the Fort Bidwell Indian Reservation

The Fort Bidwell Indian Reservation (FBIR) is rich in renewable energy resources. Development of its geothermal resources has the potential to profoundly affect the energy and economic future of the FBIC. Geothermal energy can contribute to making the reservation energy self-sufficient and, potentially, an energy exporter. The feasibility study assessed the feasibility of installing a geothermal district heating system to provide low-cost, efficient heating of existing and planned residences, community buildings and water, using an existing geothermal well, FB-3.
