60247 An inexpensive, highly regulated modulator will be required for the successful development of a heavy ion inertial fusion system. This project will demonstrate a closed-loop, amplifier-regulated driver as an induction accelerator modulator at parameters of interest to the heavy ion fusion program. Phase I demonstrated the efficacy of the closed-loop amplifier regulated driver, det ...

60419 This project will develop a three dimensional, adaptive, unstructured grid treatment of free surface magnetohydrodynamic (MHD) flow of conducting liquids, as envisioned in future fusion systems. In particular, computational fluid dynamic (CFD) tools, capable of predicting the flow behavior of conducting liquids in complex geometry with free surfaces in the presence of an intense heat ...

61066 Hazardous waste characterization, remediation, and monitoring are key missions for DOE. Conventional approaches involve cumbersome sample collection and laboratory analysis. This is time intensive and very costly, in part because of the need for experts. Crucial long-term, continuous monitoring of sites to insure that wastes do not migrate is not currently feasible. This project will ...

61063 The U.S. Department of Energy (DOE) seeks intelligent automated tuning software to improve control and functionality of plasma fusion reactors. Currently installed tokamak control systems typically fail to make use of the full potential of available equipment. These systems often require significant operator intervention to tune control action between discharges. This project will de ...

61030 As highly dense, optical-based metropolitan telecommunication networks grow, along with the concurrent need for high-speed data packet switching, lower cost, higher speed, reliable, routing/modulating devices must be found. Reliable, stable optical routing devices will bring the high speed optical network backbone closer to the end user and increase total network speed dramatically. Thi ...

60985 Carbon isotope ratio variations in carbon dioxide have been shown to be useful in mapping the flux of biologic versus terrestrial carbon sources. However, most current methods for making this determination rely upon field samples returned to laboratories for analysis, making contamination a serious problem. This project will develop new fieldable instrumentation that can make these d ...

60352 The largely unharnessed energy of tidal and ocean currents such as the Gulf Stream is enormous. The absence of an efficient, low cost, environmentally friendly apparatus for power extraction from free water currents has been the major barrier to exploitation of this renewable energy source. This project will develop a new design concept for the effective conversion of ocean curren ...

60245 Increasingly, U.S. refineries are short of hydrogen. While, untapped sources exist, including off-gas and fuel gas streams generated on-site, hydrogen recovery has been problematic. Membranes have been used for this application but membrane failure caused by plasticization and condensation of heavy hydrocarbons has led to a shutdown of a number of plants. In this project a new cl ...

This is a Phase 2 proposal to develop an instrument to simultaneously measure particle size, velocity, and concentration in applications characterized by a large size range and high particle concentration. The instrument will be based on the Pulse Displacement Technique whose feasibility was demonstrated during Phase 1. Experiments performed during Phase 1 demonstrated a high accuracy in meas ...

60513 Breast cancer is one of the major public health concerns today in the United States. However, the detection of breast cancer through mammographic screening is complicated by various anatomic factors that can hide or simulate tumors, leading to reduced sensitivity and specificity of mammography. Consequently, the rate of false negatives is 5%-6%, which results in loss of lives. The ac ...
