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 ...

WE PROPOSE TO PROVE THE SCIENTIFIC AND TECHNICAL FEASIBILITY TO USE ELECTROSTATIC ACCELERATION TO BOOST THE ENERGY OF CF-252 FISSION FRAGMENTS AS A LABORATORY SIMULATION OF COSMIC RAY EFFECTS I MICROELECTRONICS. THE PROJECT OBJECTIVE IS TO BOOST THE ENERGY SUCH THAT A LARGE FRACTION OF THE ACCELERATED IONS HAVE A RANGE IN SILICON GRATER THAN 20 MICROMETERS. THIS SOLVES A NUMBER OF PROBLEMS ASSOCIA ...

The Defense Nuclear Agency hase undertaken several related programs to develop new technologies for countering the proliferation of weapons of mass destruction, including weapons which disperse dry spore biological agents. These initiatives require an increased understanding of the response o fthese agents and their surrogates to the environments generated by various weapons, including penetratin ...

THIS DOCUMENT PROPOSES RESEARCH ON THE FABRICATION OF A FAMILY OF EMP HARDENED CONNECTORS AND CABLE HARDWARE FOR AIRCRAFT AND SHIPBOARD APPLICATIONS. THESE CONNECTORS AND CABLE HARDWARE WOULD SUPPRESS EMP TRANSIENTS THROUGH THE INTEGRAL INCORPORATION OF A THIN FILM, HIGH SPEED, HIGH CURRENT OVONIC THRESHOLD SWITCH (OTS). CABLES AND HARDWARE OF THIS TYPE WOULD SIGNIFICANTLY INCREASE THE SURVIVABILI ...

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 ...

THE DEFENSE NUCLEAR AGENCY (DNA) IS DEVELOPING THE OPERATIONAL MESOSCALE ENVIRONMENT MODEL WITH GRID ADAPTIVITY (OMEGA) TO PREDICT REAL-TIME DISPERSAL OF HAZARDOUS AEROSOLS. ONE REQUIREMENT FOR OMEGA OR ANY SIMILAR MODEL IS TO PREDICT COLLATERAL EFFECTS FROM STRIKES ON NUCLEAR, BIOLOGICAL, AND CHEMICAL (NBC) FACILITIES. THE OBJECTIVE OF THE PROPOSED PHASE I PROGRAM IS TO DETERMINE THE ESSENTIAL FE ...

We propose, in Phase I and Phase II, to build an X-ray simulator capable of easy transportation between sites which can be built for a low cost (

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 ...

NSRC PROPOSES AN AMBITIOUS EXPERIMENTAL PROGRAM DESIGNED TO INVESTIGATE FLASHBOARD PLASMA SOURCE IMPROVEMENTS WITH APPLICATION EXISTING OPENING SWITCHES IN DNA SIMULATORS. WE WILL INVESTIGATE POWER SYSTEM OPTIONS INCLUDING DC CHARGING AND EXTERNAL TRIGGER SYSTEMS WITH MODEST TRIGGER REQUIREMENTS. MODIFICATIONS TO THE ELECTRODE GEOMETRY OF THE FLASHBOARDS ARE EXPECTED TO IMPROVE DC HOLD-OFF CAPABIL ...
