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 ...

Standoff detection of nuclear materials continues to be one of the most critical tasks that security specialists must confront in a wide variety of applications, both military and civilian. There have been several approaches for standoff nuclear material detection. Each of them utilizes a different fundamental property of nuclear materials to improve the sensitivity of detection. In this SBIR prog ...

It is proposed to achieve partial conversion of the visible emission spectrum of burning aluminum into the ultraviolet range. This work is motivated by the search for effective means to defeat biological weapons by munitions employing ultraviolet germicidal radiation (UVGI). It is proposed that aluminized thermobaric formulations can be modified to deploy airborne particulates with nonlinear opt ...

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 ...

Algorithms are needed for fast-running engineering models that predict damage levels of structural members subject to the blast environment from high explosives detonated inside a building (i.e., internal explosions). These algorithms will be used as part of vulnerability analyses that quickly assess building blast damage from internal explosion scenarios associated with terrorist threats, mission ...

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 ...

Radiation tolerant Field Programmable Gate Arrays (FPGA’s) have gained wide and rapid acceptance by military and aerospace equipment suppliers; however, there are presently a limited number of chip-sets available for production and they are limited to one time programming; hence if program changes are subsequently required a backup or chip replacement is required. The lack of FPGA alternatives ...

In this SBIR Phase I/II effort, Structured Materials Industries, Inc. (SMI) will develop and demonstrate a thin film coating technology that can serve as both lethality enhancers and as functional coatings for munitions. The goal of this project is twofold: 1) we will fabricate and characterize reactive thin films that rapidly release large quantities of thermal energy and 2) we will develop a te ...

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 ...
