Applied Nanotech, Inc. (ANI) proposes to develop a novel neutron generator based on electron impact ionization from a carbon nanotube (CNT) electron source. Our proposed approach is aimed at providing significant advantages for man-portable or UAV deployment. It will provide significant advantages over existing neutron or gamma-ray sources in terms of size, weight and power efficiency without co ...

There is a need for the detection and characterization of specific radioisotopes in the interest of homeland security, treaty verification, and customs. Current high resolution spectrometers require operating temperatures at liquid nitrogen levels and are highly expensive to maintain. Other spectrometers which operate at room temperatures do not afford the resolution required to distinguish and id ...

Silicon Space Technology and team member ATK Mission Research, along with Jazz Semiconductor, propose to demonstrate a comprehensive methodology for TCAD simulation using leading-edge Synopsys tools. These tools are capable of 3-D process and device simulation, enabling Mixed-Mode simulations studies of radiation particles with silicon devices and their response to the circuit. We will collabora ...

ADVANCED STRUCTURAL MATERIALS USED IN THE FABRICATION OF SUBMARINES CAN SUSTAIN LARGE STRAINS DURING THE FORMATION PROCESS CAUSED BY EXPLOSIVE LOADINGS. THE COMPUTATIONAL SOLID MECHANICS COMMUNITY HAS RECENTRLY RECOGNIZED SERIOUS SHORTCOMINGS IN CALCULATIONS USING MATERIAL MODELS IN THIS LARGE STRAIN REGION. BECAUSE OF THE IMPORTANCE OF CALCULATIONS IN UNDERSTANDING THE SHOCK RESPONSE OF SUBMARINE ...

We propose a stochastic-finite-element based methodology to address these requirements: (i) Characterize material variability; (ii) Quantify corresponding ground-shock variability; and (iii) Design instrumentation plan. The site is discretized into N finite-elements; rock properties over this domain are characterized as the components of an N-vector stochastic field. The probabilistic characterist ...

An approach for performing high fidelity modeling for blast and progressive collapse simulations of buildings will be developed. The modeling approach will allow complete simulations of building response to be performed within several days of computing time on desktop PCs. An 'easy to use' modeling interface will also be demonstrated in this effort. All response regimes will be addressed includi ...
