Nitride-based, high-brightness, ultraviolet, visible, and white light emitting diodes are candidate devices for replacing incandescent light bulbs and fluorescent light fixtures in general illumination applications, due to their tremendous energy saving potential, long lifetime, and high efficiency. However, the poor crystalline quality of the nitride epilayers, resulting from severely lattice-mi ...

A future multi-TeV collider requires the development of new technology to achieve a much higher acceleration gradient. An active pulse compressor would enable this development by multiplying the power of Ka-band microwave pulses to obtain peak power levels that are unattainable from a single source. This active pulse compression can be achieved by rapidly switching the coupling between delay li ...

A future multi-TeV collider requires the development of new technology to achieve its high acceleration gradient. An accelerator structure that embodies a dielectric-lined waveguide, which offers the promise of sustaining a high acceleration gradient, is currently under development. However, the all-metal structures used to achieve the high acceleration gradient have encountered limits from micr ...

The efficiency of solid oxide fuel cells can be increased with anode gas recycling, leading to a lower overall system cost. Therefore, in this project, a motor driven, high-speed, high-temperature Anode Gas Recycle Centrifugal Blower will be designed, manufactured and demonstrated. A high-speed direct drive motor, combined with foil gas bearing technology, will result in a low cost, efficient, s ...

The development of improved, cost-effective Nb3Sn superconductors would have an immediate benefit for high field magnets in High Energy Physics (HEP) applications. This project will develop and demonstrate an economical powder-in-tube (PIT) Nb3Sn process for use in magnets for future HEP accelerator research. In Phase I, a low-cost, intermetallic, phase-pure Cu5Sn4 powder was developed, a PIT Nb ...
