78140S Strong radio-frequency electric fields in high-power components used in colliders can induce a resonant cascade of particles near internal surfaces (called multipacting) that can lead to surface breakdown and device failure, in some cases limiting the power than can be handled to a fraction of the design specification. Existing tools available to analyze this phenomenon have limited accu ...

Combining AED Corp. and its multi-disciplinary team's extensive and unique heavy fuel engine (HFE) hardware development experience with commercial-off-the-shelf (COTS) diesel engine components, a concept diesel engine demonstrator (CDED) will be designed. Configured to facilitate dyno test exploration of power density, heat rejection, and fuel efficiency, the lubrication, cooling, and supercharger ...

79082S High order modes in radio-frequency accelerating cavities typically degrade the performance of high-energy colliders, and consequently a significant effort is put into eliminating or strongly damping these modes. Photon band gap structures are a novel and promising approach to this problem, and integrated analysis tools that can draw on parallel computing resources are needed to accelerat ...

78103 The DOE-funded Transmission Electron Aberration-corrected Microscope (TEAM) development project seeks to achieve the imaging and analysis of individual nanostructures at atomic resolution in three dimensions (3D). Although atomic resolution tomography has been the preferred approach, an alternative approach, atom probe field ion microscopy (APFIM), has been explored for the past decade or s ...

CompuTherm proposes to develop a tool which will enable the simulation of thermal and chemical effects on turbine engine component parts made of Alloy 718 during heat treatment and service. The proposed innovative tool will include a thermodynamic database which covers all the phases for Alloy 718 and a software package which integrates both thermodynamic and kinetic models. The tool can be used t ...

THE OBJECTIVES OF PHASE I ARE TWOFOLD: DEMONSTRATE THE FEASIBILITY OF BIOLUMINESCENT TESTING FOR DETECTION OF TOXIC COMPOUNDS, AND DEVELOP AN INEXPENSIVE PHOTO-DIODE BASED LIGHT DETECTION SYSTEM FOR FIELD MEASUREMENT OF LOW LEVEL BIOLUMINESCENCE. THIS UNIQUE TEST WILL UTILIZE DARK STRAINS OF E. COLI CONTAINING CLONED LUX GENES FROM THE LUMINOUS BACTERIUM PHOTOBACTERIUM LEIOGNATHI TO DETECT CARCINO ...

We propose to demonstrate the ability to non-evasively probe the characteristics of material properties using acoustical waves through thermal conversion of a remote laser pulse. The advantages of proposed system as an inspection and identification technique are: 1) Non-contact: Sensor does not require contact with container 2) Stand-off: Sensor could be located many meters away from container 3 ...

High-performance vacuum electron devices, such as microwave tubes, are widely used in military electronic battle-space systems. These devices are found in radar, communications, remote sensing, and navigation systems, where they provide an efficient and reliable source of microwave power. The pivotal role of microwave tubes in many on-board systems makes them a natural choice for careful optimiza ...

797870 In the fast ignition concept for inertial fusion energy, high-intensity short-pulse lasers are used to create energetic particles (protons and relativistic electrons) that propagate to the fuel within a compressed capsule. The efficient transport of these energetic particles to the fuel is a key issue in fast ignition research. A combination of well-diagnosed experiments and well-tested s ...
