HIGH POWER TRANSIT-TIME AMPLIFIERS ARE A NEW CLASS OF RF SOURCE THAT CONVERTS THE KINETIC ENERGY OF AN ELECTRON BEAM INTO RF RADIATION IN A VERY EFFICIENT WAY. WHEN THE BEAM CROSSES THE CAVITY OF PROPER DIMENSIONS, IT WILL INTERACT WITH A SINGLE CAVITY MODE THEREBY RADIATING COHERENTLY AT THE MODE'S FREQUENCY. MODE GROWTH CONTINUES UNABATED UNTIL THE RF FIELDS ARE LARGE ENOUGH TO MODIFY THE BEAM O ...

ENHANCEMENT OF TAR SAND ECONOMICS REQUIRES TECHNOLOGY LEADING TO HIGH-VALUE PRODUCTS. A NATIVE PRODUCTS EXTRACTION (NPX) STRATEGY IS PROPOSED FOR SEPARATION AND PURIFICATION OF NATURALLY OCCURRING CONSTITUENTS OF BITUMEN WHICH ARE KNOWN TO HAVE HIGH MARKET VALUE. THE SEPARATION TECHNIQUES ARE OF LOW COST IN COMPARISON TO THE INCREMENTAL VALUE ADDED TO THE PRODUCT SLATE. AN ESTIMATED 50% OF BITUMEN ...

THIS PROPOSAL DESCRIBES A TECHNOLOGY WHICH WILL ELIMINATE A MAJOR SOURCE OF ERRONEOUS DATA FROM ONE OF THE MOST IMPORTANT AND COMMONLY USED DOWNHOLE LOGGING TOOLS--THE 14 MEV PULSED NEUTRON SOURCE. BASED ON AN INNOVATIVE NEUTRON DETECTOR CONCEPT, THIS TECHNOLOGY WOULD ALLOW FOR THE NORMALIZING OF DATA DERIVED FROM PULSED NEUTRON SOURCES BY MEASURING THE STRENGTH OF THE UNCOLLIDED FLUX WHILE THE PU ...

INDEPENDENTS IN THE MID-CONTINENT AREA INCLUDING OKLAHOMA AND KANSAS, NEED A NEW AND NOVEL WATER SOLUBLE POLYMER FOR INDEPTH MOBILITY CONTROL IN ENHANCED OIL RECOVERY (EOR) PROCESSES AT INTERMEDIATE TEMPERATURES OF 165 TO 200 FAHRENHEIT. PARTIALLY HYDROLYZED POLYACRYLAMIDES AND NATURAL POLYMERS HAVE HISTORICALLY BEEN THE PRODUCTS USED IN THIS REGION. AND IN ESSENTIALLY ALL OF THE EARLIER EOR PROJE ...

BLENDS OF BIOBASED FIBER SOURCES ARE MANUFACTURED AND CHARACTERIZED BY ASPECT RATIO FOR OPTIMUM PERFORMANCE IN A BIOBASED GRAFT POLYMER AS MEASURED BY MECHANICAL PROPERTIES AND SURFACE MORPHOLOGY IN COMPRESSION MOLDED TEST SPECIMENS. FROM 18 FORMULATIONS OF BIOBASED GRAFT POLYMER, THREE ARE SELECTED ON THE BASIS OF BEST OVERALL PERFORMANCE AND USED IN A BIOBASED GRAFT POLYMER COMPOSITE STUDY IN CO ...

THE OBJECTIVE OF OUR PROJECT IS TO DEVELOP NEW MEANS OF PRODUCING SHORT LIVED RADIOISOTOPES FOR POSITRON EMISSION TOMOGRAPHY (PET). THIS MEDICAL DIAGNOSTIC TECHNIQUE IS CAPABLE OF DISCERNING AND IMAGING MEDICALLY INTERESTING PHENOMENA, SUCH AS THE ACTIVITY OF VARIOUS PARTS OF THE BRAIN, OXYGEN FLOW IN THE BODY, AND OTHER QUANTITIES WHICH ARE IMPOSSIBLE TO DETERMINE BY ANY OTHER DIAGNOSTIC TECHNIQU ...

THE UNCERTAINTY IN MEASURING NEUTRON DOSE EQUIVALENT RATES RESULTS IN UNCERTAINTY IN ASSIGNMENT OF THE PROPER DOSE TO OCCUPATIONAL RECORDS AND CAN RESULT IN IMPROPER IMPLEMENTATION OF CONTROLS TO LIMIT THE EXPOSURE. A NOVEL PORTABLE NEUTRON SPECTROMETER IS PROPOSED WHICH WILL REDUCE THE UNCERTAINTY OF SUCH MEASUREMENTS TO LESS THAN 20%. MANYCOMPONENTS OF THIS DEVICE ARE COMMERCIALLY AVAILABLE. SYS ...
