65877 The generation of high power, high frequency microwaves, using conventional sources such as klystrons or traveling wave amplifiers, requires that very high field gradients be sustained in small output cavities for a long duration. A high-current electron beam source, and thus a high power modulator, is also required. This project will develop a doped diamond switch as a pulse compressor el ...

Alameda Applied Sciences Corporation (AASC) proposes to develop and commercialize stable, more durable and less expensive optical multi-layer coatings that can turn a visor into a display screen for helmet mounted display devices, with minimal impact onthe pilot's overall visual acuity. The innovation proposed is to use filtered cathodic arc plasmas to deposit high density optical coatings that a ...

Alameda Applied Sciences Corporation proposes to develop a new type of nano-thruster electric engine for highly parallel, distributed constellations of nano-satellites and other space propulsion applications. A key feature of the proposed Phase-I is theuse of an Inductive Energy Store (IES) driver to power the vacuum arc nano-thruster, which has a mass of 90% PPU efficiency from 1-10 W. The provin ...

Alameda Applied Sciences Corporation (AASC) proposes to develop a new type of high voltage, high power diamond switch potentially capable of switching GW power levels at ~100 kV. The basic element of this switch is a thin disk of natural or CVD diamondthat supports up to 25 kV, is triggered into conduction by UV radiation, achieves rise/fall times

A 24-month Phase II project is proposed to develop and implement models that capture the fidelity of high fidelity physics-based (HFPB) models in a fast-running format. It is anticipated that such models will be incorporated in certain modules of theModular Effectiveness/Vulnerability Assessment (MEVA) code developed for and currently used by the Air Force for assessing munitions effectiveness an ...

65576 Ionization chambers and photomultiplier tubes are commonly used in nuclear physics and other scientific research due to their sensitivity and energy resolution. However, these detectors provide very poor imaging capabilities. Alternatively, phosphor screens, photoemissive materials, and amorphous detectors are commonly used for imaging, but they provide poor sensitivity and energy resolut ...

60143 Multicomponent shear-wave seismic data reveal information about subsurface lithologies and fluid properties that is difficult or impossible to obtain with compressional-wave data alone. Although commercially available three-dimensional (3D), multicomponent simulations handle many aspects of the 3D behavior of shear waves in complex media, there are serious gaps. In particular, step ...

65165 The current-carrying capacity of high-temperature superconductors needs to be improved to reduce the costs and pollution associated with electric power generation, delivery, and use. Such improvements will require on-line diagnostics to detect defects in the superconducting wires as they are being manufactured. This project will develop x-ray diagnostics to provide a rapid analysis of sup ...
