THIS PROJECT INVESTIGATES A NEW TYPE OF HIGH Q RESONANT STRUCTURE, WHICH HAS RECENTLY BEEN DEMONSTRATED, TO DEVELOP HIGH GRADIENT, SUPERCONDUCTING ACCELERATOR CAVITIES. BASED ON THE CONCEPT OF A PHOTONIC BAND GAP (PBG) RESONATOR, THESE NEW STRUCTURES ARE PHYSICALLY SIGNIFICANTLY DIFFERENT FROM THE RESONANT CAVITIES CURRENTLY USED IN NORMAL SUPERCONDUCTING DEVICES. A RESONANT MODE SUITABLE FOR ACCE ...

THE USE OF THE RADIO FREQUENCY SUPERCONDUCTING ION LINACS HAS GROWN STEADILY OVER THE PAST 15 YEARS, PRIMARILY FOR APPLICATIONS IN NUCLEAR AND ATOMIC PHYSICS WHERE FLEXIBILITY N ION SPECIES AND ENERGY ARE REQUIRED. THIS TECHNOLOGY CONTINUES TO BE ACTIVELY DEVELOPED AT SEVERAL LABORATORIES WORLDWIDE. A RECENT DEVELOPMENT AT THE ARGONNE TANDEM LINAC ACCELERATOR SYSTEM (ATLAS) FOR THE NEW POSITIVE IO ...

This proposal describes a novel, high thrust density Detonation Wave Engine (DWE) applicable to the Mach range of 0 to 3. The geometry of this novel engine concept naturally provides for integration into a new Combined Cycle Engine with Ramjets. The concept is an intermittent combustion jet engine that harnesses travelling detonation waves to accomplish compression and chemical reaction. The goal ...

An innovative actively cooled structure concept is proposed which integrates proven cooling techniques and state-of-the-art fabrication methods to extend the maximum combustor wall temperature, thereby reducing cooling requirements and aircraft weight while improving engine performance. Specifically, CONvective and TRANspiration cooling (CONTRAN) are uniquely combined, relying on hydrogen coolant ...

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, ...

There is a need for non-intrusive instrumentation to characterize the drop size distribution and volume flux in support of on-line engine/inlet icing tests. The ducts may vary from three to twelve feet in diameter with flow field speeds from Mach 0.2 to 0.5. The Phase Doppler technique offers the best potential for making these measurements non-intrusively and with sufficient accuracy to meet the ...

THREE AREAS OF ACTIVE MISSILE WING RESEARCH WILL BE PURSUED. THE FIRST SECTION WILL EVALUATE THE MATERIALS TO BE USED IN THE INFLATABLE WING SPARS, RIBS, SKINS, PRESSURE BLADDERS AND ACTIVE ELEMENTS. SPECIMENS OF HIGH ORTHOGONALITY COMPOSITES (POLYURETHANE-GRAPHITE) WILL BE CONSTRUCTED ALONG WITH SAMPLE ISOTROPIC BLADDER MATERIALS (MYLAR OR TEFLON) SO THAT THEIR FUNDAMENTAL PROPERTIES CAN BE EVALU ...
