78157S Magnetic tape is no longer cost competitive with magnetic disk for storing data. However, for magnetic disk to replace magnetic tape in tape's traditional role of long term, offline data storage, a new innovative data storage architecture and system must be developed. For DOE's nuclear physics facilities that generate several hundred terabytes of data annually, and that are projected to ...

Nanophotonics promises to have a revolutionary impact on the landscape of photonics technology. Photonic crystal based structures are anticipated to play a significant role in next generation photonic devices. Incorporating the photonic crystal nanostructures provides an unprecedented opportunity to enhance the dispersion, anisotropy, and wavelength/angular sensitivity of photonic materials, which ...

75866-The difficult problems being tackled in the accelerator community are those that are nonlinear, substantially unmodeled, and vary over time. These problems would be ideal candidates for model-based optimization and control if representative models could be developed. Such models must be inexpensive to deploy and maintain, and must remain valid throughout the operating region of the system ...

This Small Business Innovation Research Phase II project will develop and deliver prototypes of high power, coherent 1550 nm Grating-outcoupled Surface-Emitting (GSE) laser array modules with integrated lenses for military detection and ranging applications. These eye-safe lasers will deliver 15 W of peak power with high coherence (relative to broad area edge-emitting lasers), wavelength stability ...

This STTR Phase I project will develop a programmable photonic integrated circuit to provide a practical hardware platform to support a robust quantum encryption system. Proposed is a two dimensional lattice structure where the architecture of the device explicitly implements quantized states as "wells" between the couplers. In operation, the proposed photonic integrated circuit will be used at ...

79546S The Spallation Neutron Source (SNS) facility, due for completion at Oak Ridge National Laboratory in 2006, will push available thermal neutron flux at least an order of magnitude above that achievable at any other neutron science facility. The markedly increased deliverable flux imposes extreme requirements on imaging detectors at many of the target stations. This project will develop a ...

79394B Superconducting radio frequency (SRF) cavities, such as those fabricated at Jefferson Laboratory and used in charged particle linear accelerators, are formed by deep drawing. In this process, a non-uniform or poorly textured microstructure in the starting sheet can cause poor deformation behavior and surface roughness in the formed part. Poor deep drawing behavior is manifested by excess ...

75778B Previous research has shown that the Ta diffusion barrier in composite Nb3Sn superconductors, such as those used in the superconducting magnets needed for fusion confinement systems, may develop a failure mode during wire drawing, due to the non-uniform deformation of the thin Ta layer. This non-uniform deformation can lead to breaches in the diffusion barrier and its premature fracture d ...

Silicon Space Technology and team member ATK Mission Research, in collaboration with Jazz Semiconductor, propose to develop and demonstrate a very deep submicron cell library and design system for radiation hardened ASICs and standard products. Specifically, we will develop a scaleable 180 nm, hardened-by-design (HBD) cell library to support the radiation-hardening of ASICs fabricated in commerci ...

StarVision Technologies proposes to conduct an experimental feasibility assessment of an innovative and robust Autonomous Aerial Refueling System (AARS). The system has been developed specifically for powered munitions and will provide significant battlefield enhancements by allowing persistent and sustained air operations. The AARS proposed is the result of several years of studies and feasibili ...
