The successful execution of the current high-capacity optical-networking environment, which supports supercomputing centers at the DOE national laboratories, requires adpative and finer-grained management/set-up of necessary bandwidth and low-delay paths between distributed applications. Whereas manual management techniques have been implemented in test beds and moderate-capacity networks, the ap ...

In order to increase proton energy up to 8 GeV in a driver linear accelerator, particles must be accelerated through various stages and three different power levels (25kW, 100 kW, and 210kw). Unfortunately, no power coupler element for these cavities has ever been produced using U.S. industrial capabilities. This project will develop innovative modular, multiple power level, 325 MHz spoke caviti ...

There are increasing demands to use high-beam-current, high-radio-frequency (RF) power, S-band cavities in existing and newly planned accelerator projects, in order to produce a very brilliant, broadband, coherent teraherz synchrotron radiation source (or for other purposes). For optimum performance, a critical technical challenge is to replace the present low-gap-voltage RF cavity with a very hi ...

Motion Sick builds on Artis, LLC's experience in portable motion recording systems, data analysis and GIS software. Artis will develop a product line that meets the needs of railroad inspectors in determining passenger ride quality and a broader market to include other transportation modes. The base product of, GPS Motion Sick, meets all the requirements specified. As with many other Artis moti ...

The superconducting radio-frequency cavities being tested for use in the International Linear Collider are made from high purity niobium sheet metal, which has an inherent, performance-hindering "damaged layer." This surface layer is removed by acid treatments, which result in hydrogen contamination and necessitate high-temperature, vacuum heat treatments. This project will develop technology bo ...

Networking and security technology have become inextricably linked as enterprises rely on computer networks for everyday operations. It is imperative to integrate several types of security technologies into the network to foil various kinds of attacks before they can do any damage. Generalized Multiple Protocol Label Switching (GMPLS) has extended Multi-Protocol Label Switching to provide the co ...

The preservation of experimental data gathered by the nuclear physics community is being compromised by the dramatic increase in the rate of data generation. Physicists need to be able to easily archive the data, along with its experimental context and their current analysis procedures, in order to prepare for future breakthroughs in analysis technology and/or potential changes of the group perfo ...

Generation-IV reactor plants have the potential to drastically reduce our dependence on foreign oil and to reduce emission of greenhouse gasses. These plants will require reliable, high-temperature physical sensors that can operate at temperatures of 800°C to 1000°C and pressures up to 1000psi, while undergoing heavy irradiation. Conventional temperature and pressure sensors in nuclear and non ...

Improved neutron dosimetry is needed to assure the safety of nuclear power plants. However, real-time spectrometers for measuring neutron dose at specific energy levels do not exist. Instead, the current state of the art relies on some type of installed neutron absorber, which must be physically removed and analyzed to obtain the energy-level specific dose. The removal process typically require ...

Wind turbine systems are increasingly being installed in extreme environments, which decrease the systems¿ efficiency and lifetimes. Two major issues affecting wind energy efficiency are blade fouling (from ice, salt, bugs, etc.) and damage from the harsh environment (corrosion, pitting from blowing sand, etc). For example, a 5% ice accumulation on the leading edge of the turbine can result in ...
