Near-field scanning optical microscopy (NSOM) is a powerful and unique approach to characterize the chemical, physical and potentially biochemical properties of materials with the nanometer scale resolution in real-time. A key element for NSOM systems that combine optical spectroscopy with scanning probe microscopy, is the actual probe itself. While many commercial vendors offer off-the-shelf meta ...

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 ...

Laser based advanced accelerators can achieve very high accelerating gradients, but their duty cycle is limited by the laser power availability and media recovery time. Inverse Free Electron Laser (IFEL) is a vacuum farfield laser accelerator scheme which does not rely on a medium (plasma) or a structure (metal or electric) and therefore is potentially capable of accelerating charged particles ver ...

Transmission electron microscopy (TEM) is one of the primary tools for biological and materials characterization; however, there is an overarching need to push TEM temporal resolution into a ps-range to study physical processes on their fundamental spatial and temporal scales. With state-of-the-art TEM, however, it is not possible to capture a single image with a temporal resolution better than 10 ...

Ensuring adequate agricultural productivity in the face of an increasing human population is a major concern with implications for both production of bioenergy products (Jones and Hinsinger, 2008) and global food security. Increasing agricultural productivity requires a stronger understanding of soil biogeochemical processes that impact plant nutrient availability. We propose development of an inn ...

Society at large and DOE in particular have an interest in the continued development and refinement of a smart grid infrastructure that more efficiently and reliably matches electrical resources to demands. While technological advances in recent years have improved the smart grid, these advances have been limited by a lack of granularity of data (e.g. environmental conditions at multiple locations ...

The rate of climate change in the Arctic is larger than elsewhere on Earth. The Arctic has unique and complex couplings and feedbacks between the surface and the atmosphere that in turn modify the radiative balance there differently than elsewhere. Current understanding holds that an increase in downwelling long wave radiative flux, driven by increased water vapor and clouds, may be accelerating c ...

The development of radiation detection materials would benefit with greater access to computational models that relate physical traits seen in manufacture with complex energy transitions occurring in the material that control operating performance. However, the HPC requirements behind these models remain beyond the reach of most businesses involved in this small yet vital field impacting National ...

Quantifying atmospheric aerosol, clouds and precipitation processes are critical needs for understanding and interpreting Earth’s changing energy budget, is a DOE objective, and is of broader benefit to the public. Specifically, the formation of ice in the atmosphere depends on the nature and abundance of ice nucleating particles, and has major implications for precipitation and cloud interactio ...
