Many planned nextgeneration experiments in high energy physics, astroparticle physics, and nuclear physics need a plethora of photon detectors with singlephoton sensitivity, large dynamic range, and accessibility throughout experiment lifetime. These requirements constrain the sensor: low sensitivity against temperature and bias fluctuations; very compact; very robust; cheap; insensitive to magn ...

Electric vehicles, including hybrids in the nearer term, are the principal transportation technology by which the United States can become independent of foreign oil, can become energy independent overall, and can effect control over greenhouse emissions. For this to become reality, electric vehicle costs need to come down and performance needs to improve. For electric vehicle motors, the goals ...

The Department of Energy and other federal agencies have made significant investments in software performance engineering tools, which can be complex and difficult to use. Novice users first encountering a tools complexity and vast array of features are intimidated and easily frustrated. There is also a lack of advanced problem identification capabilities so users rely heavily on their o ...

ScienceTomorrow in collaboration with Dr. David C Joy, at the University of Tennessee Research is proposed to fabricate direct digital Quantitative Secondary Electron Detectors (QSED) for scanning electron microscopes (SEMs). If successful, commercial versions of the QSED would transform the SEM/STEM into a quantitative, metrological tool with enhanced capabilities that, in turn, would broaden re ...

The need for ever more sensitive, compact, rugged, and inexpensive optical sensors is particularly acute in the fields of homeland security, biological sciences, nuclear medicine, and nuclear and highenergy physics. The ability to detect the spatial location and time of arrival of single photons with increased accuracy represents the ultimate goal in optical detection for many of these application ...

The Arctic sea ice cover plays a major role in governing the exchange of energy between the ocean and atmosphere in the Polar Regions. As such, observations of ice extent and thickness, including temporal growth and melt cycles, improves our understanding of the ongoing global climate changes, and enhances our ability to predict future changes. Despite continual improvements in global climate mode ...

The current installation rate of wind turbine generators is on track to meet DOE published goals of 20% wind source of electricity by 2030. As the most economical sites become populated, future installations will rely more heavily on low wind speed on-shore site locations and high wind speed off-shore or deep off-shore site locations. As higher power density evolves from 2.5 MW to 6-10 MW per turb ...

The United States Department of Energy, along with researchers in industry, and academia has identified an urgent need for Bismuth Strontium Calcium Copper Oxide superconducting precursor powder. This material is a high-temperature superconductor that will be used in powerful magnets for commercial magnetic resonance imaging devices. It is also desired to achieve very high magnetic fi ...

The TAU Performance System is a powerful and highly versatile profiling and tracing tool ecosystem for performance analysis of parallel programs. Developed over the last 15 years, TAU has evolved with each new generation of HPC systems and scales efficiently to hundreds of thousands of cores on the largest computers in the world. TAUs organic growth has resulted in a loosely coupled potpourri of ...

The U.S. Arctic continues to be one of the most difficult places on Earth for year-round scientific observations and research, and ice sheet and sea level changes have been explicitly identified as a current priority in the Presidents Climate Change Science Program, the Arctic Climate Impact Assessment, the 4th Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), and other na ...
