Accelerators used for nuclear-physics research require megawatts of radio-frequency energy. They currently employ vacuum-tube power amplifiers or conventional solid-state amplifiers that areinefficient and therefore consume a great deal of prime power. Many other applications including semiconductor processing, cellular-telephone base station transmitters and military communication systems similar ...

The native format of netCDF generated from regional climate models (RCMs) is not readily accessible or useable by the general public who may not have analytical tools to plot, visualize, or analyze the data. In response to this need, the overall long term objective of this study is to make high resolution climate change simulations model results in the North American Regional Climate Change Assess ...

This proposed work addresses the needs of a short pulse, tunable and monochromatic extreme ultraviolet and soft X-ray beamline that is table-top, low cost and easy-to-use for advanced material and nano- device studies using photoemission spectroscopy and nano-imaging techniques. The short-pulse and short- wavelength nature of this source enables capturing ultrafast dynamics in materials and nano-d ...

The development of new DOE ultrashort-pulse x-ray facilities creates exciting new possibilities for understanding dynamic processes in nature on the fundamental atomic length and length scales; i.e. sub- nm and femtosecond. However, to make full use of planned facilities such as the Short Pulse X-ray (SPX) facility planned as a major part of the Advanced Photon Source Upgrade (APS-U), correspondin ...

The Radiance lighting simulation system, primarily developed by the Department of Energy, is capable of helping teams solve a variety of problems related to daylight and energy efficiency. Nevertheless, for non-experts this platform is notoriously difficult to install and use, hence limiting its impact to industry. The technical objective is to harden Radiance for profitable commercial use. Light ...

Validation and verification (V & amp;V) is an essential part of any large scientific computing effort and of the computational physics component of the international fusion program in particular. To assist in this task, we propose the creation of a flexible eigenvalue solver that can be adapted to fluid and kinetic plasma physics models in a variety of magnetic geometries. This lightweight code c ...

Conventional indoor environmental monitoring technologies are expensive, cumbersome to install and maintain, and do not provide the distributed granularity required to capture the necessary details for efficient energy management of commercial buildings. Developments in wireless sensor networks (WSN) provide substantial framework for monitoring and addressing indoor environments at scale. However ...

The Arctic as a region of particular sensitivity to climate change. In the past few decades, the annual average temperature over the Northern high latitude land surface has risen at almost twice the rate of the global average, disrupting the region and its people. Clouds are the primary factors that influence radioactive fluxes in the Arctic, and thus the rate of warming and ice melt. Long-term i ...

Advancements are needed to improve and optimize the performance of existing and future nuclear power plants and nuclear power systems by developing and improving the reliability of advanced instrumentation. Improvements and advances are needed for systems and component technologies that ultimately would be used in the design, construction, or operation of existing and future nuclear power plants, ...

There is a need for condition monitoring sensors capable of function in the harshest environments associated with advanced power systems that will: directly contribute to improving system control, protect capital equipment investment, and promote safety through prevention of catastrophic equipment failure. These harsh environments include extreme temperatures (800-1800C), high pressures (500-1000 ...
