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 ...

Diesel/JP-8 fueled engine-generator will provide 120/208 VAC 3-phase, 60hz, 0.8PF. Of the electrical power supplied, 65% will be consumed by the ECU. The ECU will supply a max of 100K BTU/Hr of air conditioning and 60K BTU/Hr heating capacity. The system will be trailer mounted and suitable for tow behind a HMMWV in severe off-road conditions. It will be capable of 30-in water-fording with no ...

Stochastic resonance is an effect in which a nonlinear system amplifies a weak and noisy modulated signal. Some signals that are too weak for direct detection can be measured using stochastic resonance systems. This project Will examine the feasibility of developing an optical stochastic resonance detector (OSRD). A prototype OSRD will be constructed based on a photorefractive ring resonator confi ...

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 ...

79579 Because of stringent environmental regulations, the power generation industry must take measures to reduce the emission of NOx and SOx. Low-NOx burners reduce emissions by changing the combustion characteristic of coal boilers, but they increase the amount of residual unburned carbon in the fly ash. Increased carbon levels in fly ash make air-entrained concrete production more difficult , ...

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 ...

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 ...

The objective of proposal is to demonstrate the feasibility of manufacturing a coating with nearly all the performance properties of a MIL-PRF-23377 epoxy primer and a MIL-PRF-85285 urethane topcoat, particularly the adhesion, corrosion, and the weather resistance properties of those specifications. Hentzen's prototype coating will also be fast curing and near zero VOC. Hentzen believes thes ...

The work proposed will develop a Noise-Canceling Fiber Optic Microphone (NCFOM) with a digital output signal for use with AF communication systems. A first-order vented cavity NCFOM design and a dual diaphragm NCFOM design will be analyzed using already developed equivalent frequency circuits to determine the parameter values necessary for maximum directivity. Venting of the acoustic cavity or a ...
