41299 November 19, 1996 FM Technologies, Inc. In the Relativistic Klystron Two-Beam Accelerator, which is currently under development, power from a low-energy, high-current, bunched beam is converted to micro-waves via the klystron mechanism and used to provide power for a high-energy linac, specifically a future Next Linear Collider upgrade to l.0 TeV. ...

THE PLASMA BEATWAVE ACCELERATOR IS ONE OF A NUMBER OF PARTICLE ACCELERATOR CONCEPTS UTILIZING THE HIGH FIELDS INHERENT IN INTENSE LASER BEAMS. IN THIS CASE, EM WAVES INTERACT NONLINEARLY WITH AN UNDERDENSE PLASMA THROUGH OPTICAL MIXING OR RAMAN FORWARD SCATTERING (RFS) TO EXCITE LARGE AMPLITUDE PLASMA WAVES. THE PLASMA SELF-FIELDS PROVIDE THE ACCELERATION. THUS, THE CONCEPT IS A COLLECTIVEEFFECT A ...

Statement of the problem or situation that is being addressed. This proposed research project responds directly to the need of a high-efficiency continuous-wave microwave source at a frequency of 1.497 GHz delivering at least 8kW of power. This research will provide a klystron with an overall efficiency of 82% and a high degree of backwards compatibility to allow its use as a replacement for klys ...

Driven by emerging industry standards, electric utilities and grid coordination organizations are eager to seek advanced tools to assist grid operators to perform mission-critical tasks and enable them to make quick and accurate decisions. The emerging field of visual analytics holds tremendous promise for improving the business practices in todays electric power industry. However, the conducted i ...

Additive manufacturing (or 3D printing) is now becoming sufficiently accurate with a large range of materials for use in printing sensors needed universally in fusion energy research. Decreasing production cost and significantly lowering design time of energy subsystems would realize significant cost reduction for standard diagnostics commonly obtained through research grants. There is now a well- ...

THE CONTINUED PROGRESS BEING MADE IN LIQUID-METAL-COOLED NUCLEAR REACTORS REQUIRES A CAPABILITY TO MONITOR AND INSPECT REACTOR INTERNALS. SINCE THE 1960S RESEARCH IN ULTRASONIC IMAGING HAS BEEN PURSUED AT A SOMEWHAT LEISURELY PACE. SIMPLE SONIC ECHO RANGING HAS BEEN THE PRINCIPLE RELIED UPON TO GENERATE IMAGES OF INTERNALS. THIS REQUIRES A PRECISE MECHANICAL MEANS TO SCAN THE ULTRASONIC BEAM OVER ...

The potential longevity and number of dry storage systems employed for storage of used nuclear fuel necessitate a deliberate consideration of long-term data management approaches. Necessary considerations include approaches to ensure archival of data over multiple centuries and data fusion methods to facilitate decision making based on multiple streams of information. Also important is establishin ...

Statement of the problem or situation that is being addressed. The availability of ultraclean (near-zero emission), abundant, low-cost domestic energy is critical to providing economic prosperity, strengthening energy independence, and enhancing environmental quality. To accomplish this, it is required to develop a new generation of clean fossil fuel based power systems capable of producing afford ...

The use of advanced ceramic materials for light water reactor fuel cladding is being investigated, in part due to increased safety margins over conventional metallic claddings. In light of the Fukushima events, safety concerns have come to the forefront of public scrutiny of commercial nuclear generated power, spurring activity in this arena. While the safety benefits of advanced ceramics are al ...

40444 November 18, 1996 Southwest Sciences, Inc. Increasing energy consumption and environmental degradation may contribute to deleterious changes in the radiative balance and chemical composition of the atmosphere. The quantitative measurement of water vapor in the troposphere and lower stratosphere is crucial for the study of meteorological and climati ...
