All-Optical Laser-Wakefield Electron Injector

Description: Demonstrated the principle of optical control of laser accelerators, namely, that one laser pulse could modify the properties (e.g., emittance and electron number) of an electron beam accelerated by a separate but synchronized laser pulse. Another recent highlight was that, using our new 30-fs 10-TW laser system, we accelerated with a laser accelerator an electron beam with a record low divergence (0.2 degrees). This is more than 100 times lower than the 30-degree divergence that was reported r… more

Analysis of U.S. residential air leakage database

Description: The air leakage of a building envelope can be determined from fan pressurization measurements with a blower door. More than 70,000 air leakage measurements have been compiled into a database. In addition to air leakage, the database includes other important characteristics of the dwellings tested, such as floor area, year built, and location. There are also data for some houses on the presence of heating ducts, and floor/basement construction type. The purpose of this work is to identify house … more

Anisoplanatic Performance of Horizontal-Path Speckle Imaging

Description: We have previously demonstrated and reported on the use of sub-field speckle processing for the enhancement of both near and far-range surveillance imagery of people and vehicles that have been degraded by atmospheric turbulence. We have obtained near diffraction-limited imagery in many cases and have shown dramatic image quality improvement in other cases. As it is possible to perform only a limited number of experiments in a limited number of conditions, we have developed a computer simulatio… more

Description: Abstract. In 2001, a multi-agency study was conducted to characterize potential environmental effects from radiological and chemical contaminants on the near-shore environment of the Columbia River at the 300 Area of the U.S. Department of Energy’s Hanford Site. Historically, the 300 Area was the location of nuclear fuel fabrication and was the main location for research and development activities from the 1940s until the late 1980s. During past waste handling practices uranium, copper, and oth… more

Augusta Newsprint: Paper Mill Pursues Five Projects Following Plant-Wide Energy Efficiency Assessment

Description: Augusta Newsprint undertook a plant-wide energy efficiency assessment of its Augusta, Georgia, plant in 2001. The assessment helped the company decide to implement five energy efficiency projects. Four of the five projects will save the company 11,000 MWh of electrical energy (about$369,000) each year. The remaining project will produce more than$300,000 annually, from sale of the byproduct turpentine. The largest annual savings,$881,000, will come from eliminating Kraft pulp by using better pr… more
