79766S05 In order to increase proton energy up to 8 GeV in a driver linear accelerator, particles must be accelerated through various stages and three different power levels (25kW, 100 kW, and 210kw). Unfortunately, no power coupler element for these cavities has ever been produced using U.S. industrial capabilities. This project will develop innovative modular, multiple power level, 325 MHz spo ...

79784S05 In superconducting cavities used in nuclear physics research, the detection of impurities on to less than 50 micrometer sizes would enable the cavities to reach the highest possible accelerating fields. Currently available equipment can only inspect flat sheets, which allows for defective sheets to be eliminated before the expensive forming and machining of the cavity half-cells. Howeve ...

79412S05 Superconducting radio frequency (RF) cavities (of which the proposed International Linear Collider (ILC) will need several thousand) require ultra clean vacuum and surface cleanness. A break in a ceramic RF coupler window, with consequent inrushing of air and contaminants, would have catastrophic effects, and would require a long and expensive overhaul of the accelerator. To eliminate o ...

75471S Measurement techniques are needed to validate technologies developed to enhance the net long-term sequestration of carbon in man-made and natural environments. In particular, a capability is required to determine increases in carbon fixation or sequestration of 1 tonne per hectare per year. This project will develop modifications and improvements to an existing airborne remote sensing sy ...

75661S The production of hydrogen fuel from renewable resources such as solar and wind in distributed-generation, small-scale applications would provide an environmentally-benign, truly sustainable transportation fuel supply. But before this can be achieved, the hydrogen generating systems must become as reliable as home appliances (e.g., central air conditioning or furnaces), which require only ...

75616B Superconducting radio frequency cavities, used in high energy accelerators, are produced by the sheet metal forming of multiple sections, which are then joined by high-vacuum, electron-beam welding. The welding procedures are very expensive and produce flaws and contamination that limit cavity performance. Simpler approaches, based on the shaping of seamless tubes, have been hindered by ...

79369B Networking and security technology have grown inextricably linked as enterprises rely on computer networks for everyday operations. It is imperative to integrate several types of security technologies into the network to foil various kinds of attacks before they can do any damage. Generalized Multiple Protocol Label Switching (GMPLS) is used to provide the control plane for devices that c ...

79729S Ocean currents constitute a potentially enormous renewable energy resource; however, existing technologies for capturing this energy are only in the prototype stage, are small in scale (less than 1 megawatt), and are not grid-connected. Although there is a considerable overlap in technology with the more mature field of wind energy, new robust technologies will have to be developed that ar ...

79659S As direct drive wind turbines increase in size, the diameter of their generators increases to the point where it is no longer possible to ship them as a single unit. While some companies have addressed this issue by using wound rotor generators that can be assembled on site, this approach suffers from the inherent lower efficiency and reliability of the wound rotor technology. To date, no ...

75884-To increase the domestic supply of clean, renewable energy sources, the President¿s National Energy Policy and the U.S. Department of Energy¿s Strategic Plan contemplate the increased production of hydrogen as a fuel. The production of hydrogen from plant biomass is especially attractive because it is a renewable energy resource and because it recycles atmospheric carbon dioxide. However ...
