Busek Co. Inc (Busek) and Massachusetts Institute of Technology (MIT) propose to develop the design of a photon actuated, ultrafast carbon nanotube (CNT) field emission cathodes for high-power electron beam accelerator sources. The cathode will be based on massive arrays of Vertically Aligned Carbon Nano-Fibers (VA-CNFs) that are individually controlled by a vertical ungated field effect transisto ...

Electromagnetic launchers or rail guns are a key component of the Navy’s all-electric ship of the future, but they lack the durability required for repeated firings. TDA Research and the University of Nevada, Reno (UNR) are developing a tough, durable and conductive refractory metal coating that will protect the copper alloy conductors (rails) from the extreme heat and wear conditions inside the ...

Physical Sciences Inc. (PSI), in partnership with the Electrical Engineering Department of the Worcester Polytechnic Institute (WPI), proposes to compute and reduce mutual coupling between E-field antennas (in Transmit mode) and SQUIDs magnetic loops (in Receive mode) for improved signal reception in SQIF arrays. For the computation of the mutual coupling in the near field PSI and WPI will use an ...

The ever-decreasing size of the electronic microchips and the ever-increasing density of electronic components required to support future Air Force platforms are creating the problem of substantial localized heat generation that can impair component operation. State of the art thermal interface materials (TIMs), that are used to dissipate heat from the source to the spreader in a microchip, are se ...

The objective of Phase I is to identify the strengths and weaknesses of the various multi-reference coupled-cluster (MRCC) methods that have been proposed for the description of molecular states depending upon near degeneracies and non-dynamic electron correlation. Such effects are encountered in bond breaking, at transition states, for complex open shell systems like transition metal atoms, and f ...

Quantitative predictions of reactive flow dynamics from large-scale simulations of Liquid Rocket Engines (LRE) appear to be model dependent. Relationships and coupling among the dominant mechanisms most responsible for destabilization are obscured by the complexities of the model and subtle consequences of inherent ad hoc approximations not supported by mathematical rationale. The reliability of ...

The effective de novo prediction of linear and nonlinear optical properties of materials would be a great resource for developers of military and commercial optical devices. Of particular military interest are multiphoton processes that can be optimized for laser protection as well as for improving photovoltaic efficiencies above the Shockley–Queisser limit, for photodynamic therapy and for opti ...

Triton Systems, Inc. and our partners, propose to develop a commercially viable process to print high speed thin film transistors (TFTs) onto large area flexible substrates. We propose to use a commercially available deposition system to deposit high mobility semiconductors onto flexible substrates. It uses an additive process with no masks or screens necessary. The printing technology is read ...

AEDC personnel have developed and demonstrated the effectiveness of coupling a control volume model with a wind tunnel control system. The performance of the model was hampered because parameters of the model were assumed to be constant, when they are likely variables. A method for using facility data to determine functional relationships defining these parameters would allow them to vary during ...

We propose to develop a commercial weakly ionized plasma modeling capability based off of Tech-X’s high energy density plasma fluid code TxFluids. The new additions will be able to be used to model hypersonic vehicle physics including shock waves, plasma chemistry and innovative techniques for blackout mitigation and hypersonic vehicle control through the application of electric and/or magnetic ...
