Replacement of petroleum based vehicles with fuel cell electric vehicles operating on hydrogen produced from domestically available resources would dramatically decrease emissions of greenhouse gases and other pollutants as well as reduce dependence on oil from politically volatile regions of the world. One major inhibitor to a hydrogen society is the lack of infrastructure, which requires hydroge ...

The Department of Energy needs improved radiation resistant electrical insulation materials for the superconducting magnet coils in fusion reactors. To achieve safe, reliable, economic and environmentally benign fusion energy system, DOE is seeking organic/inorganic insulation-capable materials that are wrappable. These materials under irradiation will enable magnet coils to: (1) operate reliably ...

Nuclear fusion is one of humanity’s grand challenges offering a non-fossil fuel, green energy source that is inherently safe and clean. There is a critical knowledge gap in fusion energy development on how the plasma-material interface correlates to plasma performance. Driving this gap is a lack of robust, in-situ and in-process diagnostics that can measure how the composition and structure of p ...

Currently, the most promising types of radiotherapy is proton or carbon therapy, as they have demonstrated significant improvements in clinical efficiency and reduced toxicity profiles. Unfortunately, the high cost of treatments using both proton and carbon beams is the limiting factor preventing hadron therapy from becoming the standard of care for a wider range of cancers. Designing a linear acc ...

Density functional theory is used by many researchers funded by the Department of Energy as a method for predicting the behavior of chemicals and materials used in energy applications. However, results of these calculations are often not standardized and, even when they are, expert-level understand of the methods is needed in order to properly perform a simulation. The energy research community a ...

Renewable sources of energy including solar and wind are fast gaining ground on fossil fuels, in part because of their sustainability and environmental benefits. A major issue, however, has been finding efficient ways to store the energy that renewables generate for use when the demand for energy is high. Lithium-­‐sulfur batteries, which store electrical energy by transferring electrons to or ...

Thomas Jefferson National Accelerator Facility (JLab) uses low efficiency klystrons in the CEBAF machine. In the older portion they operate at 30% efficiency with a tube mean time between failure (MTBF) of five to six years. A highly efficient source (>55-60%) must provide a high degree of backwards compatibility, both in size and voltage requirements, to replace the klystron presently used at JLa ...

Metal photoinjector cathode development has shown recent promise with nano-patterning technology. However, in order to be competitive with semi-conductor cathodes, a further enhancement in efficiency is needed. TECHNICAL APPROACH Specific nano-patterning of sub-wavelength features to produce antennae provides coupling of incoming laser light with the surface of the metal cathode. Bowtie nano-anten ...

Transmission electron microscopy (TEM) is one of the primary tools for biological and materials characterization and has many important research applications. There is an overarching need to improve the temporal resolution of TEMs. State-­‐of-­‐the-­‐art single shot TEM only achieve 10 nanoseconds temporal resolution. Technical Approach UCLA and RadiaBeam Tec ...

Plasma facing components have significant challenges for fusion reactors and commercial uses of fusion energy, e.g. compact neutron generators. Economical systems have very high power densities with enormous particle flux loadings that exceed capabilities for conventional static materials, e.g. W, Mo, Cu and stainless steels. The proposed solution uses flowing liquid metal layers to transport heat ...
