Beam-based determination of the offset of Booster {gamma}{sub T} quads

Description: Twelve pulsed {gamma}{sub T} quads have been installed in the Booster to provide fast transition crossing. The less time the beam stays in the non-adiabatic period near transition, the less the longitudinal emittance grows. From the past experience, the {gamma}{sub T} quads are not well aligned relative to the usual closed orbit. Quad steering can cause beam loss and a dispersion wave after transition. To make the {gamma}{sub T} quads routinely operational, procedures for finding the center of … more

Dike/Drift Interactions

Description: This report presents and documents the model components and analyses that represent potential processes associated with propagation of a magma-filled crack (dike) migrating upward toward the surface, intersection of the dike with repository drifts, flow of magma in the drifts, and post-magma emplacement effects on repository performance. The processes that describe upward migration of a dike and magma flow down the drift are referred to as the dike intrusion submodel. The post-magma emplacement… more

Novel Optical Detection Schemes for In-Situ Mapping of Volatile Organochlorides in The Vadose Zone

Description: The long-term objective of this research is to develop a system for measuring and identifying a wide rang of volatile organic hydrocarbons, including organochlorides, at ppb levels in-situ in the subsurface (''at-dept'') using a fiber-optic REMPI probe. In this renewal proposal we would also like to expand the range of analytes to include contaminated soil and certain metal pollutants such as Hg and Pb. And, to do this in a ruggedized system that is compatible with existing fiber-optic sensors,… more

Thermal Management and Analysis for a Potential Yucca Mountain Repository

Description: In the current Yucca Mountain repository design concept, heat from the emplaced waste (mostly from spent nuclear fuel) would keep the temperature of the rock around the waste packages higher than the boiling point of water for hundreds to thousands of years after the repository is closed. The design concept allows below-boiling portions of the pillars between drifts to serve as pathways for the drainage of thermally mobilized water and percolating groundwater by limiting the distance that boili… more

Study of the effects of high temperatures during quenches on the performance of a small Nb(3)Sn racetrack magnet

Description: Several high field Nb{sub 3}Sn magnets of different design are under development for future particle accelerators. The high levels of stored energy in these magnets and the high current densities in the conductor can cause high peak temperatures during a quench. The thermal gradients generated in the epoxy-impregnated magnet coils during the fast temperature rise can result in high thermo-mechanical stresses. Considering the sensitivity of Nb{sub 3}Sn to strain and epoxy cracks, it is important… more

Nb3Sn accelerator magnet development around the world

Description: During the past 30 years superconducting magnet systems have enabled accelerators to achieve energies and luminosities that would have been impractical if not impossible with resistive magnets. By far, NbTi has been the preferred conductor for this application because of its ductility and insensitivity of Jc to mechanical strain. This is despite the fact that Nb{sub 3}Sn has a more favorable Jc vs. B dependence and can operate at much higher temperatures. Unfortunately, NbTi conductor is reachi… more

The highly successful safe remediation of the Fernald waste pits undertaken under the privatization model

Description: Remediation of eight waste pits at the Department of Energy (DOE) Fernald site, located northwest of Cincinnati, Ohio, involves excavating approximately one million tonnes in-situ of low-level waste which were placed in pits during Fernald's production era. This unique project, one of the largest in the history of CERCLA/Superfund, includes uranium and thorium contaminated waste, soils and sludges. These wet soils and sludges are thermally dried in a processing facility to meet Department of Tr… more

Accurate modeling of cache replacement policies in a Data-Grid.

Description: Caching techniques have been used to improve the performance gap of storage hierarchies in computing systems. In data intensive applications that access large data files over wide area network environment, such as a data grid,caching mechanism can significantly improve the data access performance under appropriate workloads. In a data grid, it is envisioned that local disk storage resources retain or cache the data files being used by local application. Under a workload of shared access and hig… more

Pulsed ti: sapphire laser power amplifier

Description: We have demonstrated an all solid state Ti:Sapphire laser system consisting of a power oscillator and single pass amplifier. The electrical-to-optical efficiency far exceeds that of the current CW systems. The pump lasers have lower capital and operating costs than the Argon-ion laser. In the future, we plan to scale the output power to higher levels by adding a fourth pump laser and improving the output power of the current pump lasers. Modeling results suggest that a large increase in efficie… more

Measured Winter Performance of Storm Windows

Description: Direct comparison measurements were made between various prime/storm window combinations and a well-weatherstripped, single-hung replacement window with a low-E selective glazing. Measurements were made using an accurate outdoor calorimetric facility with the windows facing north. The doublehung prime window was made intentionally leaky. Nevertheless, heat flows due to air infiltration were found to be small, and performance of the prime/storm combinations was approximately what would be expect… more

Application performation evaluation of the HTMT architecture.

Description: In this report we summarize findings from a study of the predicted performance of a suite of application codes taken from the research environment and analyzed against a modeling framework for the HTMT architecture. We find that the inward bandwidth of the data vortex may be a limiting factor for some applications. We also find that available memory in the cryogenic layer is a constraining factor in the partitioning of applications into parcels. The architecture in several examples may be inade… more

Well-to-tank energy use and greenhouse gas emissions of transportation fuels vol. 1, 2, 3.

Description: There are differing yet strongly held views among the various ''stakeholders'' in the advanced fuel/propulsion system debate. In order for the introduction of advanced technology vehicles and their associated fuels to be successful, it seems clear that four important stakeholders must view their introduction as a ''win'': (1) Society, (2) Automobile manufacturers and their key suppliers, (3) Fuel providers and their key suppliers, and (4)Auto and energy company customers. If all four of these s… more
