Award Data

methyst Research Inc. will design, fabricate and test a high uniformity, large area, low noise infrared trap-detector detector for the 1- 4.5 μm wavelength range. This state of the art detector will have a large area (e.g., 1-1.8 cm diameter active area) with a spatial variability of internal quantum efficiency of less than 0.1 % between 1 μm and 4.5 μm. In addition, the internal quantum effici ...

Wind power plays an increasingly important role in satisfying the power needs of the U.S., and serves to reduce dependence on fossil fuels. With increased penetration, significant maintenance costs and reductions in power generation have underscored the need to predict the unsteady loading related to turbine configuration, layout and off-design wind conditions as well as importance of accounting ...

Biological, chemical and geological activity of soils and groundwater impact agriculture, hydrology, and climate. Sophisticated computer models now include a multitude of interactions that can simulate the complex nature of near, subsurface regions. Improved measurement methods are needed both to provide accurate data to those computer models and to test model predictions. Ideal instruments wil ...

Statement of the problem or situation that is being addressed through phase I of the proposal: High performance optical networks are needed by DOE and commercial entities. The high performance optical networks need higher speed (>100Gb/s), low power consumption lasers. The proposed approach addresses that need. General statement of how this problem is being addressed. The objectives of phase I is ...

Statement of the Problem or Situation that is Being Addressed Current and future data centers and high-performance computing (HPC) centers need optical communication links to transmit the aggregate data rates that are generated by servers. For these, applications current optical gears that are designed for telecommunication applications are expensive, take large space and do not match to small for ...

Statement of the problem: The fundamental requirement for interconnect is to meet the high-speed needs of chips despite further scaling of feature sizes, while the main function of an interconnect system is to distribute clock and/or other signals among various circuit functions on a chip. As the clock has been doubling its present speed over a period of less than half a decade, current interconne ...

Project Summary: Driven by bandwidth hungry technologies such as online video and cloud computing, the skyrocketing growth of global data traffic has no sign of halting. The total amount of content passing through the worlds networks will increase from 800,000 petabytes in 2009 to 35 zettabytes in 2020. To meet the worlds endless appetite for bandwidth, dense wavelength division multiplexing (DWDM ...

Statement of the Problem Isotopologues are a critical tool in monitoring plant hydrobiogeochemical and microbial systems and processes. The most abundant elements utilized and exchanged by plants, microbes and ecosystems are carbon (C), hydrogen (H), oxygen (O) and nitrogen (N), all of which have naturally occurring stable isotope forms that can be used as natural tracers for understanding and int ...

Statement of the Problem or Situation that is Being Addressed: Metals released into the environment from industrial processes, roadways and automobiles, belong to a class of persistent environmental toxins that often remain in contaminated locations for a long time. Water containing trace amounts of radioactive materials is also normally released from U.S. nuclear power plants under controlled, mo ...

PROJECT SUMMARY The US Department of Energy (DOE) Office of Nuclear Science is actively seeking improved designs for cryogenic structural support systems that can achieve up to a 5 to 10x reduction in heat load, while still being able to tolerate radiation doses up to 100 MGy, without degradation in its mechanical and thermal performance. In addition, the cryogenic support systems must not only ma ...
