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

Alameda Applied Sciences Corporation proposes to develop and test a capillary discharge source of KCl as an alternative to Ar gas puffs for Decade Quad. The innovative feature of such a capillary source is that the initial z-pinch load is highly ionizedand well collimated, as demonstrated earlier with a NaF source on Gamble II and Double-EAGLE (DE). Consequently, the stability and radiation effici ...

Alameda Applied Sciences Corporation (AASC) proposes to adapt a commercially available instrument called a Laser Wavefront Analyzer (LWA) to capture snap-shots of the current and density in the initial coronal region of an imploding z-pinch on the 0.7 MAHawk accelerator at NRL. These snap-shots will reveal the structure of instabilities in the formation of the pinch and allow us to correlate impro ...

Reliability and structural safety are major concerns in the design of next-generation space transportation and systems. Acellent Technologies, Inc. Proposes to develop and innovative, cost-effective and reliable built-in structural diagnostic system forlight-weight large-scale space structures made of composite materials to monitor their integrity during service thereby prolonging life span, red ...

A six-month Phase I project is proposed to demonstrate the feasibility of a hierarchical method for more accurately estimating the material parameters of constitutive models in DYNA3D, thereby enhancing the fidelity of nonlinear finite element models. Thehierarchical approach combines the distinct advantages of coupon, component and system-level testing with Bayesian statistical parameter estimat ...

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 ...
