Superconducting Radio Frequency (SRF) structures used for particle accelerators typically operate between 4 – 2 K, i-e- cryogenic temperatures, and are sensitive to microphonics that create length oscillations in the accelerating structures- To keep the SRF cavities on resonance under the influence of distortions in the SRF cavities caused by microphonics, RF power above what is required for acc ...

There is a lack of cost-effective and easy-to-use tools and services for complex data streams which is characterized by multi-dimensional features including large data volumes, variety, velocity and veracity that are commonly referred to as BigData- BigData creates a scalability challenge for environmental system solutions that use traditional relational databases to perform organization, retrieva ...

Increasing the volumetric capacity of hydrogen storage is critical to bringing fuel-cell powered vehicles to market- High-pressure, compressed-hydrogen tanks are large, heavy, and expensive- High-pressure compression is also costly, energy-intensive, potentially hazardous, and is made even more challenging due to the non-idealities of hydrogen gas at elevated pressures- Physical adsorption of hydr ...

Actionable understanding of watershed and ecosystem behavior is required for a wide spectrum of societal and engineering needs by both government entities and commercial entities- These needs include, for example, water resource management, precision agriculture and hydropower- Such actionable understanding requires the ability to numerically model various coupled processes and associated reaction ...

The United States depends on its fleet of nuclear facilities for the clean and reliable generation of electricity- With the increased and growing need of electricity, additional nuclear facilities can provide the solution Generation IV Reactors, such as Advanced Small Modular Reactors (SMR’s) are an upgraded means to nuclear thermal energy production- These SMR’s can provide up to 300 megawatt ...

A major problem facing the existing U.S. fleet of Light Water Reactor facilities is stress corrosion cracking of austenitic nickel and iron alloys, which comprise the bulk of wetted components in LWR facilities; up to 70% of wetted non-fuel areas in a typical facility, making this problem particularly widespread and especially prevalent with extended service life. Cold spray technology offers an e ...

The Department of Energy’s Office of Nuclear Physics Isotope Development and Production for Research and Applications Program has identified a need for materials that will survive high radiation environments to support next generation rare isotope beam facilities. Specifically, long-lifetime, rotary vacuum and water seals are needed to survive 0.5 – 15 MGy/month. Current gaskets and seals do n ...

Redox sensitive heavy metals - chromium, iron, manganese, and copper have attracted a great deal of attention around the world for their impact on human health and environment. It is beneficial to study the temporal dynamics of metal ion concentrations and coupled biogeochemical reactions. Traditional systems are expensive to use with costly and bulky instruments, and are not suitable for field mo ...

There are increasingly greater legislative, social, and environmental factors motivating the use of clean energy technologies that reduce carbon dioxide and other greenhouse gas emissions, with fossil fuel power plants collectively producing the largest fraction of carbon dioxide. The high costs associated with separation are prohibiting the application of carbon capture due to high energy and inf ...
