FOR THE CLASS OF DNA NUCLEAR WEAPONS EFFECTS SIMULATOR KNOWN AS THE PLASMA RADIATING SOURCE (PRS), HIGH RESOLUTION X-RAY SPECTROSCOPY DIAGNOSTIC MEASUREMENTS PROVIDE CRITICAL INFORMATION BOTH FOR CHARACTERIZATION OF THE TEST-OBJECT RADIATION ENVIRONMENT AND FOR OPTIMIZATION OF THE SOURCE. PRESENT PRS HIGH RESOLUTION X-RAY SPECTROMETERS RECORD DATA ON PHOTOGRAPHIC FILM, THE PROCESSING AND ANALYSIS ...

COMMERCIAL SAPPHIRE SURFACES CONTAIN BURIED DAMAGE WHICH HAS A DELETERIOUS INFLUENCE ON SOS LAYERS GROWN THEREON. THE DEFECTS IN THE SILICON LAYERS RESULT IN A REDUCED YIELD OF DEVICES AND PERFORMANCE LIMITATIONS. MUCH OF THE DAMAGE IN THE SAPPHIRE SURFACE IS PRODUCED BY THE POLISHING STEP, WHICH EMPLOYS AN ABRASIVE PAD IN CONTACT WITH THE SAPPHIRE SURFACE. AN IMPROVED POLISHING PROCESS HAS BEEN E ...

NEAR-SURFACE DEFECTS IN SEMICONDUCTORS HAVE A PRIMARY INFLUENCE UPON DEVICE PROPERTIES, PARTICULARLY THE YIELD. IT WOULD BE VERY USEFUL TO BE ABLE TO MAP SPATIALLY THE DENSITY AND TYPE OF DEFECTS NEAR A SEMICONDUCTOR SURFACE EITHER AS A WAFER QUALITY CONTROL STEP OR TO SUPPORT DEVICE PHYSICAL EXPERIMENTS. CONVENTIONAL TECHNIQUES USED FOR THIS PURPOSE SUFFER FROM ONE OR MORE OF THE FOLLOWING LIMITA ...

THERE IS A NEED FOR A GOOD STRUCTURAL CERAMIC MATERIAL THAT CAN BE USED AT HIGH TEMPERATURES IN THE OXIDIZING AND CORROSIVE ATMOSPHERE OF TURBINE ENGINES AND THAT CAN BE FORMED ECONOMICALLY TO COMPLEX SHAPE WITH LOW WEIGHT. THE OBJECTIVE OF THIS RESEARCH PROJECT IS TO INVESTIGATE A NEW FAMILY OF CERAMIC COMPSITE MATERIALS THAT MAY MEET THOSE REQUIREMENTS. IT IS BASED ON CHEMICALLY VAPOR DEPOSITED ...

SEAFLOOR DEPOSITS OF COBALT-RICH FERROMANGANESE CRUST WITHIN THE U.S. EXCLUSIVE ECONOMIC ZONE OFFER A POTENTIAL NEW MINERAL RESOURCE FOR STRATEGIC METALS. EVALUATION OF THESE DEPOSITS IS A PRIME OBJECTIVE OF CURRENT AND PLANNED DEPARTMENT OF INTERIOR RESEARCH EFFORTS. PRESENT CRUST SAMPLING DEVICES ARE INADEQUATE FOR EFFICIENT RESOURCE ASSESSMENT. THE DEVELOPMENT OF A TETHERED, MULTI-SAMPLE CORING ...

PROJECTILE PULSE GENERATOR (PPG) HAS BEEN CONCEIVED TO SATISFY ANTICIPLATED AIR FORCE REQUIREMENTS. THE PPG IS EXPLOSIVELY DRIVEN AND IS INTENDED TO MEET THE REQUIRMENTS STIPULATED IN THE SBIR
