The objective of this program is to develop a silicon-on-insulator technology (SOI) using CVD diamond films as insulators. Such structures should permit the fabrication of integrated circuits with performance capabilities superior to those fabricated using conventional SOI structures including silicon-on-Sapphire (SOS), SIMOX, Epitaxial Layer Overgrowth (ELO) and Bond Etchback SOI (BESOI). Diamond ...

The availability of energy storage capacitors with high energy densities (>1- kJ/kg AND >15 MJ/m3) is critical for many applications. existing capacitor designs use laminated assemblies which are impregnated with liquid dielectrics. However, since the dielectric strength of liquids is generally much less than for solids, the maximum operating electric field is limited by the impregnant. This, in t ...

INTEGRATED CIRCUIT (IC) PRODUCTION LINES OPERATING UNDER MIL-I-38535 HAVE RADIATION HARNESS ASSURANCE (RHA) AND RELIABILITY DESIGNED AND BUILT INTO THEIR TECHNOLOGY. HARDNESS AND RELIABILITY ARE MAINTAINED BY APPLYING STATISTICAL PROCESS CONTROLS (SPCS) TO TEST STRUCTURES FABRICATED ALONGSIDE PRODUCT MICROCIRCUITS. MEASUREMENT AND DATA REDUCTION TECHNIQUES PRESENTLY EMPLOYED ARE SLOW AND COSTLY AN ...

PHYSCIAL OPTICS CORPORATION (POC) PROPOSES TO FABRICATE A NUCLEAR HARDENED SCINTILLATING DETECTOR (NHSD) FOR PRECISE DETECTION AND MONITORING OF RADIATION AT CRITICAL LOCATIONS SUCH AS NUCLEAR POWER PLANTS, ATOMIC WEAPON PRODUCTION FACILITIES AND NUCLEAR WEAPON TEST SITES. THE PROPOSED NHSD IS BASED ON INTEGRATING ORGANIC FLUOR, SOLGEL TECHNIQUES AND DIAMOND-LIKE COATING TECHNOLOGIES. BY OPTIMIZIN ...

THE DEFENSE NUCLEAR AGENCY (DNA) IS DEVELOPING THE OPERATIONAL MESOSCALE ENVIRONMENT MODEL WITH GRID ADAPTIVITY (OMEGA) TO PREDICT REAL-TIME DISPERSAL OF HAZARDOUS AEROSOLS. ONE REQUIREMENT FOR OMEGA OR ANY SIMILAR MODEL IS TO PREDICT COLLATERAL EFFECTS FROM STRIKES ON NUCLEAR, BIOLOGICAL, AND CHEMICAL (NBC) FACILITIES. THE OBJECTIVE OF THE PROPOSED PHASE I PROGRAM IS TO DETERMINE THE ESSENTIAL FE ...

Visidyne proposes to develop an expert, neural net based, system for extrapolating satellite imagery forward in time to provide short-range forecasts of cloud cover. In Phase I Visidyne proposes to investigate the limits of the temporal extrapolation of satellite cloud imagery. For locations in a variety of climate zones, Visidyne will determine how long overlying clouds can be tracked backward in ...

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 ...

Accuwave Corporation will study the feasibility of a volume holographic, phase-encoded optical image correlator for credit card and document validation and security application. Fourier transform holograms of a phase-encoded input image are stored using wavelength multiplexed holographic gratings in a photorefractive crystal. High spatial resolution images can be sotred with low crosstalk using ...

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 ...
