WE PROPOSE TO SEARCH FOR NEW SUPERCONDUCTORS THAT ARE SIMILAR TO THE PEROVSKITE-BASED HIGH TEMPERATURE SUPERCONDUCTORS (HTS), BUT WITH THE OXYGEN REPLACED BY A CHALCOGEN, THAT IS SULFUR, SELENIUM OR TELLURIUM. WE BELIEVE THAT THE HTS COPPER OXIDES ARE NOT A UNIQUE ACCIDENT OF NATURE, BUT THAT THERE ARE OTHER COMPLEX CHEMICAL COMPOUNDS THAT COULD ALSO BE SUPERCONDUCTING. AN OBVIOUS PLACE TO LOOK WO ...

THE CONTRACTOR SHALL DEVELOP A FUZZY SET METHODOLOGY FOR UNCERTAINTY ANALYSIS IN PROBABILISTIC SEISMIC SAFETY ASSESSMENT OF NUCLEAR POWER PLANTS. FUZZY SET LOGIC WILL BEUSED FOR COLLECTING, QUANTIFYING AND PROPAGATING SUBJECTIVE,ENGINEERING JUDGEMENT USED IN THE UNCERTAINTY ANALYSIS. IN PHASE I, FEASIBILITY OF THE PROPOSED APPROACH WILL BE DEMONSTRATED BY APPLYING IT TO SELECTED PARTS OF A PROBABI ...

A new approach to generating atomic hydrogen (and possibly N and O) will give atomic fluxes of 10(-19) atoms/cm(-2) over a three inch wafer positioned three inches in front of the source. Scalt up to larger areas may be possible in phase II. We will examine the use of this source as an alternative to hot filament assisted generation of atomic H for diamond thin film growth. Use of the source for M ...

Ionwerks has begun an internally funded project to design and manufacture an MBE growth chamber specifically designed and optimized for wide bandgap nitrides (compatible with Si/Ge growth also). This chamber will include two proprietary growth techniques which we have found to be crucial for formation of cBN thin films. Design and construction of this chamber is underway. We will use this equipmen ...

This proposal addresses an approach to millimeter wave imaging called encoded image detection (EID). The concept offers a means of achieving a low cost, all weather seeker for smart munition and submunitions. Its low cost potential makes adaptation of the imager also attractive for a variety of other military applications such as search and rescue, surveillance, and security. Most current devel ...

This Phase I SBIR demonstrates the underlying technology required to construct an ultraspectral imager that has the ability to spectrally resolve molecular absorption lines while simultaneously creating a two dimensional spatial mapping. The proposed instrument will have a spectral resolution that is better than 2 cm-1 and two dimensional spatial resolution that exceeds 2 milliradian. Based on Fou ...
