Adroit Systems, Inc. will develop a Pulse Detonation Synthesis (PDS) process to manufacture ceramic powders from gas-powder reactant mixtures more efficiently and inexpensively than current methods. A high combustion rate and simple design make the PDS system capable of mass producing these powders, which are used as raw materials for high-temperature, high-performance ceramics and ceramic composi ...

This Phase I project has two primary objectives. The first objective is to evaluate the feasibility of a fully ion implanted fabrication process based on the heterodimensional 2-D MESFET. The new device, the 2-D JFET, will have p+ ion implanted sidegates which laterally modulate a thin, highly doped n-type conducting channel. The 2-D JFET should have excellent high speed, low power characteristics ...

Development of reliable (Q-) switching and isolation materials is being sought for near-to-mid infrared lasers for safety, extended life and fiber optic communication. The voltage or E-field controlled (Q-) switching materials such as Pockels cells and liquid Kerr cells are not reliable for long term operation in tactica applications due to crystal surface (e.g., KDP, ADP) degradation by moisture ...

Electronic devices which operate at high temperatures could be used in many military and commercial systems. GaAs and Si based devices cannot operate at these temperatures and require cooling. Wide bandgap material such as diamond, SiC and GaN have greater breakdown voltages, higher operating temperatures, and higher saturated electron velocities than either GaAs or Si. However, these material sys ...

High voltage semiconductor devices have found important applications in the areas of high power generation, power control, power conversion, surge protection, and industrial electronics. However, GaAs or Si based high voltage device are limited by a relatively low intrinsic breakdown voltage and,therefore, inherently suited for high power applications. We propose to develop novel high voltage hete ...

NEMP (Nuclear Electro-Magnetic Pulse), lightning strikes, high powered EMI (Electro-Magnetic Induction), or ESD (Electro-Static Discharge) can impress high transient voltages on wires connecting to electronic modules. These transients are potentially destructive to aircraft electronic components and can result in system failures. To eliminate or substantially reduce the effects of transients on ...

If you can't beat them, join them. Such is the philosophy of Space Exploration Associates, who hired the top talent in Russian and the new Republic of Georgia to develop advanced thermionic converters for SDIO. Unlike other highly publicized exchanged with the Russians, this work will be done in the US and no hardware will cross international lines. The metallurgical wizards from the East have con ...

Everybody knows that composites have high strength, low density, and great thermal properties. They would be great for a number of applications such as fins for spacecraft radiators. So why aren't they used more on spacecraft thermal systems? One reason is joining technology. Although many methods such as brazing and adhesives have been developed for joining composites to metals, these methods are ...

Phase I proposes to demonstrate an easy-to-operate, inexpensive room temperature neutron detector based on boron-doped diamond. The detector would produce an immediate signal related to low-level neutron irradiation. The concept exploits the high neutron absorption cross section of B-10, which results in excellent sensitivity. The charge carriers generated in the diamond by a neutron absorption ev ...
