Alameda Applied Sciences Corporation (AASC) proposes to develop a new type of trigger for a high voltage, high repetition rate diamond switch. AASC has previously developed diamond switches with electron beam triggers. These switches handle 10-20 kV voltage pulses with

This Small Business Innovation Research Phase I project will develop refractive x-ray lenses for medical, industrial, scientific, and directed-energy applications. Previously, ordinary optical refractive lenses were assumed to not work at x-ray wavelengths because refractive effects were very small. Reflective and grazing angle techniques are usually limited to the soft x-ray region of the spectru ...

The objective of this effort is to create new, low-cost, UV-imageable/thermosetting polymers for optical waveguides printed circuits that can be fabricated using conventional printed wire board fabrication processes. Benefits of these new polymers are (a) adjustable refractive in-dices. (b) high optical transparency with low optical losses, (c) exceptional thermal and me-chanical properties, (d) h ...

A decision aid system is a computer application that solves complicated problems that would otherwise require extensive human expertise. To do so, it simulates the human reasoning process by applying specific knowledge and inferences. The highly demanding requirements of the newer and future all-source decision aid system can be met by the integration of various decision making approaches. The pri ...

Aluminum Nitride (A1N) substrates are attractive for III-nitride epitaxial growth due to their high thermal conductivity, close lattice and thermal expansion match to IlI-nitride compositions used for opto-electronic and electronic devices and their relative ease of growth when compared to Gallium Nitride (GaN). Vapor sublimation is an attractive method for growing A1N bulk crystals. Seeded growth ...

Aerosol generation is an important leading edge technology with relevance to ballistic missile defense because of the importance of bioearosol generation technology in the development of countermeasures for defence against biological warfare. Aerosol delivery is also an important route for the transmission of naturally occurring particulate materials. The development of new technology for the effi ...

The ultimate objective of this research is to develop a low cost, high bandwidth, quickly deployable communications system. The system relies on 10-20 Mbps RF communications within a 100 m diameter cell size. The cells are interconnected with 622, Mbps optical crosslinks. The critical technology in making these cross links feasible with low installation cost is that they be self-aligning. In this ...

The objective of this research is to investigate the use of photon-counting avalanche photodiodes as a laser communication sensor. This detector technology allows reduction of the received optical power. The system will also incorporate a cesium atomic line filter to eliminate background light and a wavelength locked communication laser matched to the atomic line filter. This configuration will en ...

The increased complexity of the modern electronics increases size. which reduces speed because of time delays in the interconnects. As a result. for frequencies above a few GHz, asynchronous communication between subsets of a complex system is unavoidable. The disadvantage of this approach is the need to recover the phase (clock) of the digital signal, which for semiconductor circuits requires a f ...

Conductus proposes to develop high-quality hiqh-temperature superconducting (HTS) thin films on polycrystalline substrates for high-frequency applications. The approach will utilize a novel technology based on ion-beam assisted deposition (IBAD) for biaxial texturing of oxide films currently under investigation at Stanford University. IBAD will be used to deposit oriented buffer layers on poly-cry ...
