High-field (~5 T) bent-dipole (0.7 m radius) magnets are required as part of a 180-degree-bend beam-transport region in the high radiation areas of a planned Rare Isotope Accelerator (RIA). The requirements for these magnets can be met by using a novel coil design called the double-helix dipole (DHD). The double-helix approach offers a solution to the design of these curved magnets that is much ...

Higher Field Magnets, used in high energy physics (HEP) research, demand higher field materials such as Bi2212 round superconducting wire. The Bi2212 wire-manufacturing process depends on the coil-fabrication method and wire-insulation material. For example, the wind-and-react method requires the coil to be uniformly heated to the melt temperature and uniformly cooled to the solidification tempe ...

High-performance optical networks play a pivotal role within the DOE complex by enabling high-bandwidth communication and collaboration over long distances. The problem, however, is that optical networks do not have the same buffering capacity as electrical networks, and, thus, they require new techniques and protocols to share optical links. Many current techniques result in poor network utiliz ...

There is a need to accelerate the technology for sequestering green house gas (GHG) emmissions from coal-fired electrical-generating plants, thereby reducing global warming. One sequestration option involves the injection of GHG into coalbeds. A straightforward inexpensive method is needed to predict the amount of CO2, NO2, and SO2 (all GHG components) that can be sequestered in unmineable coalb ...

At the present time, no federated search engine exists that is capable of searching, aggregating, and ranking more than a small fraction of the scientific content produced by the research community at large and by DOE researchers in particular. Although thousands of sources of valuable content exist, a solution has not been developed that ensures that scientific discoveries already made can be ea ...

High Energy Physics (HEP) experiments face major challenges in building interactive analysis environments for the unprecedented volume of data that will be gathered in the next generation of experiments at the Large Hadron Collider (LHC) and other accelerators. The current generation of HEP Grid infrastructures is largely aimed at the initial event reconstruction and analysis phases and may not b ...

In the U.S., the annual production of 4.6 billion pounds of nylon starts with the liquid-phase oxidation of 3.5 billion pounds of cyclohexane to KA-oil (a mixture of cyclohexanone and cyclohexanol) and the subsequent oxidation of the latter to adipic acid with HNO3. The liquid-phase cyclohexane process, which operates at only 4-10% cyclohexane conversion, is the ¿least efficient¿ industrial pro ...

The data storage market constitutes a sizeable and rapidly growing facet of the world economy, and worldwide data storage needs are growing at an unprecedented rate. New technologies are needed to keep up with the demand for affordable, efficient, and permanent (archival) digital storage. This project will develop a new type of data storage system that uses very thin layers of material to perman ...

Because investment in the United States power-grid infrastructure has not kept pace with increased energy demands, existing power lines must operate close to conservative safety limits. Advanced instrumentation can simultaneously improve efficiency and maintain reliability by enabling true dynamic rating, identifying grid operational instability, and improving operator response to contingencies. ...

More sensitive detection methods leading to early diagnosis could significantly impact the treatment of cancer and other diseases and dramatically increase survival rates. However, current methods used to detect disease indicators do not have the needed sensitivity and often are effective only once the indicator concentration has reached a critical level. Nanotechnology-enabled probes, which can ...
