Alameda Applied Sciences Corporation (AASC) proposes to develop an all-solid-state, compact, portable, multi-gigawatt poer modulator for electron and ion beam diodes, high power microwave and x-ray sources. This modulator is based on Inductive Energy Store (IES) using an array of Diamond Opening Switches for power compression. Because power amplification using IES requires a much smaller volume ...

Alameda Applied Sciences Corporation (AASC) proposes to develop a new type of interferometer that is compact and portable and can be used to make in-situ measurements of gases and plasmas. This interferometer uses polarization maintaining optical fibers and diode lasers to duplicate the capabilities of existing Mach-Zender interferometers that use dicrete optical elements such as mirrors, lenses ...

184 Diamond Fast Opening Breaking Switches--Alameda Applied Sciences Corporation, 2235 Polvorosa Avenue, Suite 230, San Leandro, CA 94577-2249; (510) 483-4156 Dr. Rahul R. Prasad, Principal Investigator Dr. Mahadevan Krishnan, Business Official DOE Grant No. DE-FG03-97ER82320 Amount: $74,989 Alameda Applied Sciences Corporation will develop a fast-opening breaking switch to improve the heati ...

This proposal seeks to demonstrate the feasibility of using impulse radar techniques to detect and identify explosive detonators. It relies on the fact that a radar impulse will excite natural electromagnetic resonances which characterize the size, shape, and material composition of an object. These resonances are present in the scattered transient return from the object and can be extracted by ...

RECENT WORK IN VOLUME HOLOGRAPHY HAS LED TO THE DISCOVERY OF THE ORTHOGONAL DATA STORAGE TECHNIQUE. THIS METHOD OF HOLOGRAPHIC DATA RECORDING REDUCES THE CROSSTALK BETWEEN CHANNELS BY STORING MANY WAVELENGTH MULTIPLEXED IMAGES IN A PARTICULARLY EFFECTIVE USE OF K-SPACE. FURTHER REDUCTION IN CROSSTALK IS OBSERVED IN HOLOGRAMS STORED IN CERTAIN PHOTOREFRACTIVE CRYSTALS USING THE COUNTER-PROPAGATING ...

Accuwave Corporation has developed a narrow bandwidth (1/8 angstrom) optical imaging filter operating in the red. A critical need exists for narrow bandwidth imaging filters with a wide field of view. In this proposed research effort, Accuwave filter technology will be extended to a wider field of view using multimple holograms stored in a LiNb03 crystal.

The recent DNA-sponsored conference on ¿Verification and Validation of Nonlinear Structural Dynamic Codes,¿ September 1993, highlighted the need for reliable models as well as codes. At the present time there are no generally available software tools for utilizing experimental data to correct and refine models implemented on general-purpose codes such as DYNA3D. Nor are there tools available f ...

ADAPTIVE DIGITAL ARRAY PROCESSING IN AIRBORNE RADARS CAN PROVIDE A MAJOR IMPROVEMENT IN TARGET DETECTABILITY BY ADAPTIVELY SUPPRESSING CLUTTER AND JAMMING. THE EFFECTIVENESS OF THIS SPACETIME ADAPTIVE PROCESSING HAS BEEN DEMONSTRATED BY DETAILED SIMULATION AT ASI. RECENTLY, ARRAY RADAR FLIGHT TEST DATA WAS USED TO VERIFY THE PERFORMANCE OF ADAPTIVE RADAR. THE PROPOSED STUDY WILL EXTEND THE SIMULAT ...
