Award Data

There is a growing need for new SPM techniques that provide additional information about the sample with higher data rates. In microwave harmonic scanning tunneling microscopy (MHSTM) a microwave signal is coupled to the STM, and several harmonics that are generated by the nonlinearity of the tunneling junction are measured to provide spectroscopic information about the sample such as identifying ...

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 ...

Innovative Confinement Concepts (ICC), like the spheromak and the field reversed configuration (FRC), provide an opportunity to study magnetic confinement in geometries other than the tokamak and may provide an alternative path to fusion energy. Many ICCs require a pre-ionizer or plasma injector in order to improve shot-to-shot repeatability. A pre-ionizer must meet several critical criteria so th ...

This Small Business Technology Transfer Phase I project is proposed to address high temperature superconductor insulation to help improve stability and quench protection. Most importantly stability will be increased so that the power level at which quench occurs is greatly increased. Quench is the rapid, unintended transition from superconducting to normal conducting. It is a consequence of a faul ...

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 ...

This proposal addresses the problem of measuring and mapping saturated hydraulic conductivity in the top 100 m of the subsurface. Hydraulic conductivity is a critically important property controlling groundwater and contaminant movement. The ability to measure and map hydraulic conductivity in the near subsurface, in a cost effective way, is essential to the remediation and long-term stewardship o ...

Global Technology Connection, Inc., in collaboration with academic partners, Georgia Tech"s Center for Innovative Battery and Fuel Cell Technologies, Penn State University, and industrial partner Eagle Picher propose to create a physics-based modeling for predicting the life performance of Low and Middle Earth Orbit (LEO/MEO) Lithium-ion cells. The relationships between solid-electrolyte interpha ...

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 ...

Cermet, in collaboration with researchers at Georgia Institute of Technology, proposes to implement a lattice matched III-Nitride technology using existing substrates. The implementation of a lattice matched substrate promises to produce near dislocationfree III-Nitrides for the first time while the use of an existing substrate technology dramatically lowers development cost and reduces the devel ...

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 ...
