73137-Future active imaging systems for national security applications (for remote reconnaissance, monitoring and characterization of hard targets, and compact surveillance devices) require compact, rugged, and efficient short-pulse laser sources that can operate over a wide-repetition-rate range. To deploy these devices on ground, air, and space platforms, the new laser sources are required to i ...

75352-Many DOE sites require the monitoring of radionuclide contamination in surface water, groundwater, soils, and the vadose zone ¿ often in real-time and with remote monitoring capability. However, existing site characterization procedures typically involve the collection and shipment of samples to an off-site laboratory, leading to costly delays in site remediation as well as to increased ri ...

72743-In the past, power converter/inverter designs (such as those used in electric or hybrid electric vehicles) tended to be application-specific engineering projects, which limited their utility because the low-volume production of specialized power conversion equipment significantly increased design risk and development cost. On the other hand, todays power electronics technologies lend themse ...

75239-Landfills are the single largest source of anthropogenic methane emissions in the United States, producing 7 million tons or 34% of the total methane pollution. According to the Intergovernmental Panel on Climate Control¿s Third Assessment Report, methane has a Global Warming Potential 23 times that of CO2 and is a key contributor to global climate change. This project will develop techno ...

75374-In response to the DOE¿s desire to identify spin-off technology from its Magnetic Fusion Energy program, this project addresses the identification of unexploded ordnance, using a nuclear assay with neutrons produced by fusion reactions. In particular, a portable neutron source will be developed that is capable of detecting high explosives, particularly unexploded ordnance (UXO) and landmin ...

75252 The development of fusion energy would be quickened if spin-off applications could be identified and commercialized. In this spirit, this project will develop a nuclear assay that uses a high intensity neutron source based on an inertial electrostatic confinement (IEC) plasma device developed by the DOE Office of Fusion Energy Sciences. The nuclear assay will address one of the most criti ...

75471-Measurement techniques are needed to validate technologies developed to assure the long-term sequestration of carbon in man-made and natural environments. In particular, a capability is required to determine increases in carbon fixation or sequestration of 1 tonne per hectare per year. This project will develop an airborne remote sensing system that can meet these resolution and accuracy g ...

75470-The sequestration of carbon is a major world-wide goal for reducing the greenhouse effect. New, low cost methods are needed for determining and verifying carbon sequestration and for lowering its overall cost. Existing biomass and carbon survey methods and technologies are too slow, too expensive, and too inexact. This project will develop a very high frequency (VHF) synthetic aperture ra ...

72383-Conventional waveguide windows for extremely high-power microwave systems are close to their power-handling-capability limits. Further efforts along conventional lines invite problems with higher-order modes, thermal cooling, and thermo-mechanical stresses. The basic problem with the conventional approach is that the microwave power is forced through a single disk window. This project wil ...
