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 ...

Alameda Applied Sciences Corporation (AASC) proposes to develop a new class of real time integrating diamond radiation dosimeters. In Phase I AASC will demonstrate the feasibility of using diamond radiation detectors for monitoring personnel radiation dose. The sensitivity of these detectors will be determined and a concept design for a pocket real time dosimeter will be completed. The Phase ...

THE EMERGING IMPORTANCE OF NUCLEAR-WEAPON AND DIRECTED ENERGY WEAPON (DEW) EFFECTS TESTING IN THE SOFT X-RAY REGIME HAS HIGHLIGHTED THE NEED FOR A ROBUST, ACCURATE AND RELIABLE SOFT X-RAY SPECTROMETER THAT WILL MEASURE FLUENCE INCIDENT ON UGT TEST-ARTICLES. THE NEW LAYERED SYNTHETIC MICROSTRUCTURE (LSM) X-RAY INTERFERENCE MIRROR TECHNOLOGY IS PROPOSED AS THE BASIS FOR A SPECTROMETER RESPONSIVE TO ...

The nuclear weapons community has traditionally focused on the next generation or level of weapon capability complimented by gathering and analysis of actual test data. Now, with the cessation of actual weapons testing, there is an increased need to use the actual test data in modeling techniques to better understand the phenomenology and potential effects of nuclear weapons. The first phase of ...

DEVELOPMENT OF AN INNOVATIVE AND ECONOMICAL EXPERIMENTAL METHOD IS PROPOSED WHICH CAN PROVIDE THE BASIC BEHAVIOR DATA NECESSARY TO MEET THE DNA OBJECTIVE OF PROVIDING ADEQUATE ANALYSIS, DESIGN AND ASSESSMENT METHODS FOR MINIMALLY HARDENED TUNNELS. THIS DEVELOPMENT IS ACCOMPANIED BY ANALYSIS CAPABLE OF REPRESENTING THE COMPLEX INELASTIC MATERIAL BEHAVIOR OF THE ROCK MASS AND OF REPRESENTING SIMPLE ...

Turbulence of gas flows by its very nature is one of the most difficult things to model and measure. We propose to develop a new way of measuring the turbulence and to compare these measurements to predictions using the k-epsilon model. Typical measurements, in the past, use smoke, Schlierin or shadow graph techniques to visually infer turbulence characteristics. These features are either motio ...
