72699 Next-generation high flux neutron sources, such as the Spallation Neutron Source at Oak Ridge National Lab., will allow faster-than-ever data collection rates. Present generation of neutron sample environment equipment (cryostats, furnaces, etc.) lacks the automation features needed to handle the high demand by non-expert users for rapid experiments, and frequent sample changes. This pro ...

76276-The particle physics communities, working on the CERN Large Hadron Collider (LHC) Project2, are building infrastructures to support the processing of distributed datasets that require Petascale computing resources (>1015 bytes, and >1015 flops). This project will contribute to this endeavor by developing a formal process language and associated process execution environment targeted specifi ...

75697-Heavy ion interactions with magnets, strippers, collimators, fragmentation targets, and mass separators have an important impact on the design of a facility such as the RIA (Rare Isotope Accelerator). Calculations to assess performance and radiological impact require not only heavy ion transport in material media, but also coupled transport in an electromagnetic field. Currently, no engine ...

72180-Future energy-frontier accelerators depend on the development of robust and affordable techniques to quickly reduce the size of a muon beam. Although schemes exist to reduce horizontal and vertical muon beam dimensions, no satisfactory solution exists to quickly shrink the beam bunch length or momentum spread, as required for a Muon Collider or as would be cost-effective for a Neutrino Fact ...

75497-Ionization cooling, a method for shrinking the size of a muon beam, is needed for muon colliders and neutrino factories, two options for future High Energy Physics facilities. Hydrogen is needed in these applications for several reasons, but a safe and efficient containment cryostat is a prerequisite for its use. This project will develop a single hydrogen system to provide ionization ene ...

75496-If the case for a muon collider as the next energy frontier machine can be made compelling, it becomes a candidate to be added to other options for the High Energy Physics community. However, the proton drivers used to produce the required muon intensity are expensive and difficult, and the decays of the large number of muons in the storage ring make experiments extremely difficult. The ke ...

75498-Ionization cooling, a method for shrinking the size of a particle beam, is an essential technique for future particle accelerators that use muons. Muon colliders and neutrino factories, examples of these future accelerators, depend on the development of robust and affordable techniques for ionization cooling. Unlike schemes now under consideration, which are based on using many large flask ...

75355-Near term Heavy Ion Fusion (HIF) experiments require the development of a set of subroutines that are suitable for the straightforward insertion into existing simulation codes. This project will develop a subroutine for one such code, LSP, which will provide lookup of charge exchange and ion stripping, especially multi-electron stripping transport. In Phase I, data will be mined from exper ...

75356-Existing Inertial Electrostatic Confinement (IEC) fusion devices are not yet efficient due to current limitations attributed to ion confinement time, low reaction rates, and electron loss rates. These limitations may be overcome by combining particular IEC confinement geometries with the advantages of the closed field line system of a magnetic dipole. Accordingly, this project will develop ...

75781-Over the past 40 years, the DOE and other government agencies have invested significant funding into the research and development of a wide range of robust, high quality, numerical algorithms for scientific computation. To maintain and support this wealth of high quality software, in the face of enhancements in computer architectures and changes in scientific applications, a more formal mec ...
