NOVA Scientific, Inc., teamed with the Electronics Group of Oak Ridge National Laboratory, proposes to construct very large area Microchannel Plate neutron detectors. The applications of these much larger format detectors will serve an exceptionally broad range of government agencies from neutron scattering detectors for DOE to nuclear material panel detectors for NNSA, and ultimately to nuclear m ...

Solvent extraction by hexane is the most common choice for extraction of oil/lipids from algae. However, hexane is not the best choice of solvent for algae oil extraction because of the need to market byproducts for human and animal consumption. Oil and hexane from the solvent extraction process are separated by distillation/evaporation which is an energy intensive operation. Presence of explosive ...

Future magnets for Fusion Energy Systems require superconducting cables with improved high critical current carrying capacity at high magnetic fields, 20 Kelvin operation, low AC losses and lower cost. A new method of fabricating a high current cable with 2G HTS tapes has been developed that will improve the engineering current density achievable. Commercial Applications and Other Benefits: Fut ...

An innovative, super-miniature, fast-switching array-based photonic time delay device is being developed for the active electronically scanned-array (AESA) MDA and Navy radars. The design is based on the fast electro-optic effect, the super miniature fiber-lens collimation array, and the existing WDM photonic true time delay technologies. In Phase I Agiltron has successfully demonstrated the core ...

Silicon has long been the semiconductor of choice for high-voltage power electronic applications. Recently, SiC has attracted attention because SiC is projected to have better performance than silicon. [1] SiC power switching devices have yet to becommercialized, largely due to SiC crystal defects, most notably the device-killing micropipe defect, which does not permit high total current parts t ...

Beam diagnostics capable of measuring the transverse and longitudinal phase space are needed for the diagnosis of the new generation of accelerators being developed for high energy physics and advanced light sources. These devices all employ highly relativistic, intense, high energy accelerators. Traditional devices used to map the beam phase space such as ¿pepper pot¿ collimators cannot be ...

High energy accelerators, used for nuclear physics, high energy physics, and advanced light sources, produce beams with both low emittance and small spatial size. The high average power of these beams preclude the use of conventional interceptive diagnostics and make it very difficult to monitor beam properties in real time. This project will develop a novel non-interceptive diagnostic based upon ...

Recent clinical trials have cast doubt on the efficacy of Boron Neutron Capture Therapy (BNCT) for brain tumor treatment when low energy, reactor-generated neutron beams are used. It has been predicted that higher energy, accelerator-produced neutron beams would have an epithermal neutron spectrum that would be much more effective. Therefore, this project will design and fabricate an innovative ...

A random access, solid-state, optical cross-switch capable of 770 channel discrimination in the telecommunications C-band is designed and proven as an alternative to current thin-film WDM devices and as a mechanically robust alternative tomicroelectromechanical (MEMS) WDM devices. The device may be used in multiplexing (mux), demultiplexing (demux), or complete cross-switch configurations, and is ...

The wide-bandgap semiconductors GaN and SiC hold great promise for high temperature and highpower electronic devices. This is due to the attractive properties these materials possess, such as wide energy bandgaps, high breakdown fields, high thermalconductivities, and high saturated electron velocities. In addition, GaN and SiC have adequate electron mobilities and can readily be doped n and p ty ...
