Alameda Applied Sciences Corporation (AASC) proposes to develop an all-solid-state, compact, portable, multi-gigawatt poer modulator for electron and ion beam diodes, high power microwave and x-ray sources. This modulator is based on Inductive Energy Store (IES) using an array of Diamond Opening Switches for power compression. Because power amplification using IES requires a much smaller volume ...

Alameda Applied Sciences Corporation (AASC) proposes to develop a new type of interferometer that is compact and portable and can be used to make in-situ measurements of gases and plasmas. This interferometer uses polarization maintaining optical fibers and diode lasers to duplicate the capabilities of existing Mach-Zender interferometers that use dicrete optical elements such as mirrors, lenses ...

Prasad, Principal Investigator Dr. Mahadevan Krishnan, Business Official DOE Grant No. DE-FG03-97ER82320 Amount: $74,989 Alameda Applied Sciences Corporation will develop a fast-opening breaking switch to improve the heati ...

This proposal seeks to demonstrate the feasibility of using impulse radar techniques to detect and identify explosive detonators. It relies on the fact that a radar impulse will excite natural electromagnetic resonances which characterize the size, shape, and material composition of an object. These resonances are present in the scattered transient return from the object and can be extracted by ...

We propose to engineer a low-cost computer-controlled optical diagnostic system for measuring sound speed, thermal diffusivity, density, and velocity. This system will use laser-induced thermal accoustics (LITA), a transient-grating technique capable of making accurate single-shot measurements in luminous, multiphase, high-pressure flows. The LITA signal intensity is quadratic in fluid density f ...

129 Integrated 2-D Silicon Detector for High-Count-Rate, Low-Noise X-Ray Applications--ARACOR, 425 Lakeside Drive, Sunnyvale, CA 94086-4704; (408) 733-7780 Dr. Yuzhong June Wang, Principal Investigator Mr. Ed LeBaker, Business Official DOE Grant No. DE-FG03-97ER82330 Amount: $75,000 Detectors used for nuclear physics research, synchrotron applications, and analytical x-ray instruments are cur ...

The goal of this two-phase program is to develop a prototype system which addresses the problem of nondestructively extracting layout patterns for multilayer printed circuit boards. The system will use x-ray digital tomosynthesis for image acquisition, and advanced image processing, including morphological operators, to extract circuit features from the images. The objectives of Phase I are to 1 ...

We propose to develo a numerically efficient rotorcraft trim and transient response algorithm. The algorithm is intended for application in a periodic dynamic system with a large number of degrees of freedom as is commonly the case in current comprehensive rotorcraft analysis codes (such as 2GCHAS). The innovation of this proposal can be summarized as follows: 1) Utilizing Model Order Reduction ...
