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 ...

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 ...

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 ...

To reach high luminosity in a collider, its beam must be focused into a small-size spot at the interaction point (IP). Achieving such a small focal spot size requires expanding the beam to a rather large size at the final focusing quadrupoles. This is space consuming and leads to large chromaticity and chromatic beam smear at the IP. Compensating these chromatic effects proved challenging because ...

The development of new rare isotopes production schemes, which are simple and can be implemented at low cost, is highly desirable for Nuclear Physics facilities such as FRIB. The Munich Accelerator for Fission Fragments (MAFF) project developed an interesting idea of using a position with high neutron flux near the core of a nuclear research reactor to drive fissions in a small UCx (1.2 grams of 2 ...

Magnets in the fragment separator region of the Facility for Rare Isotope Beams (FRIB) facility would be subjected to extremely high radiation and heat load. Critical elements of FRIB are the dipole magnets which select the desired isotopes. Since conventional NiTi and Nb3Sn superconductors must operate at ~4.5 K, the removal of the high heat load generated in these magnets will be difficult. More ...
