65805 High rate energy storage devices, such as ultracapacitors, are a critical enabling technology for hybrid electric vehicles (HEV). The best electrode materials for use in electric double-layer capacitors (EDLC) possess three characteristics: (1) high surface area; (2) high electrical conductivity; and (3) surface area easily accessible by electrolyte. While ruthenium-based ultracapacit ...

70211 The high magnetic fields required for future accelerator magnets can only be achieved with Nb3Sn or other A15 or HTS type conductors, which are brittle and sensitive to mechanical strain. The traditional ¿cosine-theta¿ dipole configuration for these magnet designs has intrinsic drawbacks that make it difficult and expensive to employ such conductors. These drawbacks include: ...

70326 Beam transport in inertial fusion induction accelerators requires reliable, compact, and low cost superconducting quadrupole arrays. These multiple beam transport systems are interleaved with induction cores for acceleration, which poses unique requirements on the magnet-interconnect regions, the array cryostat, and the beam vacuum system. This project will design, build, and test a ...

70860 Current drilling systems (e.g., steerable systems and rotary steerable tools) have limitations when drilling deep wells, particularly in applying high torque to the drill bit. Steerable systems generate a high degree of drag from hole tortuosity, and rotary steerable tools have reduced bit torque also due to drag. Other systems (e.g., percussion) develop high vibrations which can dama ...

70794 Monitoring the non-proliferation of nuclear weapons requires the detection of penetrating radiation emitted by nuclear materials (NM). Gaseous ionization chambers, based on collecting the charge produced by the ionizing radiation inside the detecting medium, are widely used to detect this radiation. To eliminate the dependence of pulse-height distribution at points of interaction, ...

70558 The control and dynamic operation of Fuel Cell/Turbine Hybrid power plants will require a synergy of operation between subsystems, increased reliability of operation, and reduction in maintenance and downtime. Futhermore, the control strategy of the power plant will play a significant role in system stability and in ensuring the protection of equipment to promote maximum life. T ...

65568 The successful development of high quality plastic wavelength-shifting optical fibers coupled to a plastic scintillator for nuclear and high energy particle detection applications has created a need for compact, high-gain, high efficiency detectors in the visible and near-infrared. Visible light photon counters (VLPCs), fabricated several years ago, showed significant promise but suf ...

65201 Carbon nanotubes of uniform structure and properties are highly promising new materials for energy production, storage devices, and many other applications. A new type of carbon nanotube with two tubular layers (double-wall carbon nanotube, DWNT) shows improved physical properties over previous nanotube structures; however, an efficient method to selectively produce this unique carbon na ...
