73137S03-IFuture active imaging systems for national security applications require compact, rugged, and efficient short-pulse laser sources that can operate over a wide-repetition-rate range. These systems can generate high-resolution topographical maps, which can help detect the proliferation of weapons of mass destruction. However, to achieve adequate range and resolution in airborne and space ...

72383S03-I Conventional waveguide windows have power-handling limitations that severely restrict linear accelerator performance. This project will develop a novel microwave window concept that directly addresses the electrical and thermal stress limitations of conventional waveguide windows, leading to improvements in both peak and average power-handling capability. Phase I will develop a desig ...

72102S03-I In order to comply with current EPA regulations for reducing the level of sulfur in gasoline and diesel fuel, domestic refineries will need to install new process units for desulfurization of the fuel streams. However, current commercially available desulfurization technologies have significant energy requirements due to the severe operating conditions (such as high temperatures and p ...

70880S02-II The cost of wind energy has declined dramatically in the past 20 years and is now closely competitive with more conventional sources of electrical energy. This project addresses the need to further reduce the cost of wind energy, by developing an innovative rotor design for commercially available, megawatt-scale wind turbines. In order to reduce loads without increasing system cos ...

70075T02-II Significant fuel cost savings can be realized in the automotive and aerospace industries by employing lightweight materials in the design and fabrication of vehicular components. To date, the exploitation of lightweight magnesium and aluminum alloys in component fabrication has been restricted due to their limited formability at room temperatures in conventional metal stamping proc ...

72259S03-I The proposed target for heavy-ion-driven inertial fusion energy (IFE) consists of a spherical capsule suspended in the middle of a cylindrical hohlraum. The capsule must be accurately located (¿ microns) by two ultra-thin membranes which must have high strength, high radiation resistance, good cryogenic properties, and low cost. While polyimide can meet all of these stringent requir ...

72564S03-I The nuclear physics research supported by DOE has a fundamental need for instruments that detect photons (x- and gamma rays). Segmented germanium detectors can provide better position and energy resolution than any other practical detector system. Although no fundamental technical roadblocks should prevent the ultimate production of commercially viable instruments based on segmented ...

72560S03-I New window materials that can handle multi-megawatt radio frequency (RF) powers are needed to increase the reliability of RF windows for linear particle accelerators. Aluminum nitride would be an excellent window material due to its high thermal conductivity, high dielectric strength, low secondary electron emission, and high mechanical strength if its dielectric loss (loss tangent) c ...
