Increasing the steam temperature of supercritical boilers from 1,000F to 1,400F can raise the operating efficiency of next-generation AUSC coal-fired power plants from about 32% to about 42% and address compelling environmental issues, while also enhancing national security, domestic employment, economic stability, balance of trade and U.S. GDP through increased use of domestic coal. Low Cr conten ...

Conventional Li-ion cells/batteries for hybrid and electric vehicles have difficulty meeting USABC goals for performance/cost that are required for commercially-viable EV. The prevailing large format pouch/prismatic has the advantage of low packaging weight/volume, 10% at cell level, but is doubled (100% increase) in transitioning to the battery. Aside from the reduced energy density (accommodatio ...

One of the major cost elements of todays Lithium Ion Batteries and Ultracapacitors is the cost of manufacturing the electrodes. A significant reduction in cost is a major goal of the DOE Vehicle Technologies Program. Reducing the cost of these storage devices could accelerate the use of HEV, PHEV, and EV vehicles in the U.S. transportation sector. One of the major contributors to the manufacturing ...

Near-field scanning optical microscope (NSOM) offers the use of a nano-dimension light energy source with a diameter much smaller than the wavelength of light to achieve resolutions significantly (around 10 times) better than that of the usual optical microscope. NSOM has found wide usages and become an important measurement instrument for nano-technologies, nano-manufacturing, optical technologie ...

Multiphase bubbly mixture flows in pipelines, cooling equipment, reaction towers, and in petroleum, chemical, geothermal and nuclear industries have strong influence on efficiency. The ability to predict the flow behavior accurately is essential in designing energy efficient two-phase flow processing and transporting equipment. One of the major prediction difficulties lies in the complex multiple ...

Future large scale sciences are anticipated to use massive amount of data in their experiments. DOEs ESnet (Energy Science Network) is developing a 100 Gbps backbone based on this state-of-the-art 100 Gigabit Ethernet standard. ESnet will serve thousands of DOE and non-DOE scientists with its high bandwidth backbone, and connect several national laboratories. Current Ethernet test and debug soluti ...

A 200 kW CW fundamental RF power coupler (FPC) with an adjustable in situ coupling factor would be highly desirable for a number of applications; for example, the 352 MHz light source at APS. The normal process of adjusting the coupling by rotational movement usually requires breaking the vacuum between the coupler and the RF cavity resulting in prolonged down-times and the risk of introducing con ...

Current and future synchrotron radiation light sources and free electron laser facilities are in need of improvements in Electron Gun Technology, especially regarding the cost and efficiency of photoinjectors. Novel electron gun features are needed to enhance the intensity and reduce the emittances of electron bunches produced at a high repetition rate using laser excitation. The generation of Sur ...

State of the art high intensity proton accelerators require the development of low cost, reliable RF sources with phase stability of less than 1 degree and amplitude control of +/- 15%. These power sources feed superconducting RF cavities for linacs capable of accelerating protons and ions up to several GeV. A two-stage phase-locked magnetron RF source based on the principle of reflection amplifie ...

The development of H- ion sources with performance exceeding those achieved today is a key requirement for the next generation of high power proton accelerators. Project X at Fermilab needs a CW H- Ion Source that satisfies demanding performance specifications: 10 mA CW beam current with normalized transverse rms emittance 0.2 mm mrad, fast chopping capability, fast intensity variation, and long ...
