THE OBJECTIVES OF THE PHASE I EFFORT ARE TO QUANTIFY THE EFFECT OF X-RAY SCATTER ON RADIOGRAPHIC IMAGE QUALITY, TEST SCATTER REJECTION APPROACHES, AND GENERATE A CONCEPTUAL DESIGN OF A SYSTEM WHICH WILL PROVIDE BETTER RESOLUTION, CONTRAST SENSITIVITY, AND DYNAMIC RANGE THAN IS CURRENTLY AVAILABLE WITH COMMERCIAL REAL-TIME RADIOGRAPHY SYSTEMS. PRESENTLY, REAL-TIME RADIOGRAPHY SYSTEMS DO NOT REJECT ...

DARPA AND THE U.S. SEMICONDUCTOR COMMUNITY ARE ACTIVELY DEVELOPING LASER-PRODUCED PLASMA (LPP) X-RAY SOURCES AS THE BASIS FOR X-RAY MICROLITHOGRAPHY EXPOSURE SYSTEMS. THESE LPP SOURCES WILL ALLOW THE CONSTRUCTION OF COMPACT EXPOSURE SYSTEMS THAT CAN BE EASILY INTEGRATED INTO EXISTING SEMICONDUCTOR FABRICATION LINES, AT A COSTSUBSTANTIALLY LESS THAN THAT OF COMPARABLE SYNCHROTRON EXPOSURE BEAM-LINE ...

THE SCANNING PHOTOVOLTAGE (SPV) TECHNIQUE IS A NON-DESTRUCTIVE, HIGH RESOLUTION OPTICAL METHOD FOR MAPPING ELECTRICALLY-ACTIVE DEFECTS IN SEMICONDUCTORS. THE POTENTIAL OF THE SPV TECHNIQUE HAS NOT BEEN REALIZED FOR MODERN, ULTRA-THIN FILM MATERIALS, HOWEVER, BECAUSE OF MULTIPLE REFLECTION INTERFERENCE EFFECTS WHICH MASK THE DEFECT-RELATED SIGNALS. MEASUREMENTS ARE FURTHER HAMPERED BY LOW SIGNAL-TO ...

THE PROJECT IS DEVELOPING A MICROMECHANICAL CONSTITUTIVE DAMAGE (MCD) MODEL FOR USE WITH METAL-MATRIX COMPOSITES. THE MODEL INCORPORATES TRADITIONAL PARAMETERS SUCH AS AN ELASTICVISCOPLASTIC MATRIX, FIBER-MATRIX DEBONDING, RESIDUAL STRESSES, AND FIBER PACKING GEOMETRY. THE MCD MODEL INCORPORATES CONTINUUM MODELS OF FRACTURE AND FATIGUE AT THE LOCAL FIBER-MATRIX LEVEL. THE MODEL INCREASES UNDERSTAN ...

THE DEVELOPMENT OF A NOVEL NON-SCANNING WAVELENGTH DISPERSIVE SPECROMETER (WDS) FOR ANALYTICAL ELECTRON MICROSCOPY (AEM) IS THE OBJECTIVE OF THIS PROJECT. THIS SPECTROMETER IS DESIGNED TO PROVIDE SUFFICIENT ENERGY RESOLUTION OVER BROAD REGIONS OF THE SOFT X-RAY SPECTRAL REGION (FROM 100 TO 2000 EV) TO ALLOW THE OBSERVATION OF THE K-EMISSIONS OF THE LIGHT ELEMENTS (THOSSE WITH ATOMIC NUMBERS LESS T ...

THIS PHASE I PROJECT WILL DEVELOP A DETECTOR TECHNOLOGY FOR TRACKING PARTICLES CLOSE TO THE BEAM PIPE IN NEW GENERATION ACCELERATOR EXPERIMENTS. HIGH SPATIAL RESOLUTION, HIGH SPEED DATA READOUT, COMPACT SIZE, LOW POWER, AND RADIATION HARDNESS WILL BE ACHIEVED BY INCORPORATING A HIGH RESISTIVITY, DETECTOR GRADE, 300 MUM THICK WAFER PATTERNED WITH P(+) DETECTOR ELEMENTS INTO THE RADIATION HARDENED, ...

The U.S. Navy has a need for improving the defense of their ships and components through high risk/payoff technologies. Self defense can be greatly improved by using measures to control the electromagnetic signatures of Navy platforms. There has yet to be developed, a truly adaptive, multi-spectral solution. This project is to develop several material options through sputtered thin film deposition ...

THIS RESEARCH WILL EXECUTE AN INDEPTH STUDY OF THE BASIC FEATURES OF EMBEDDED SYSTEM AND PLANT PROCESS SOFTWARE, INCLUDING ITS INTERACTIONS WITH THE HARDWARE SYSTEMS THAT IT IS INTENDED TO CONTROL AND REGULATE. THE PURPOSE OF SUCH A STUDY WILL BE TO IDENTIFY THE PROCEDURES AND ANALYTICAL TECHNIQUES, TO BE INTEGRATED IN AN EMBEDDED SYSTEM SOFTWARE ANALYSIS METHODOLOGY, THAT CAN BE OF GREATEST UTILI ...
