OBJECTIVE: To provide innovative technologies and system components which increase the lifetime and utility of various systems within DTRA"s Tag, Track, and Locate (TTL) portfolio to combat weapons of mass destruction (WMD). The specific innovations sought under this topic are improved technologies that advance the state of the art for energy scavenging or capture from the ambient environment an ...

The development of a high-shock data recorder for use in projectile penetration and pyrotechnic environments is critical to understanding the loads that warhead systems are exposed to in tactical applications. Data from recorders mounted inside warheads can be used by researchers to measure loads on the warhead, fuze, and explosive fill components as well as validate analytic and computational mo ...

"Reflex triode bremsstrahlung sources potentially provide warm X-ray sources (20 keV to 500 keV), capable of generating high doses (~10 cal/g gold) over exposure areas of ~20 cm2. This needed capability allows experimental verification of warm X-ray inducedthermomechanical response, SGEMP, and box IEMP models for achieving component and system certification to hostile environments.In a reflex trio ...

"Nuclear Weapons Effects Tests (NWET) frequently require that the test article be irradiated in an ultra-clean environment, making survivable shields a necessary part of many debris systems. Survivable shields as large as 12 inches in diameter are requiredbut have yet to be demonstrated in Plasma Radiating Source (PRS) environments. The loads on a survivable shield are a combination of radiation i ...

"Measurements of fluence from a Plasma Radiation Source (PRS) are critical to the performance of accurate Nuclear Weapon Effects (NWE) experiments. Fast, total stopping calorimeters have been demonstrated to provide a robust, reusable, economic sensor forfluence measurements. However, the output of these sensors is a few millivolts and thus high signal to noise recording is difficult to achieve, ...

Future efforts to verify arms control agreements will require new technologies that are self-contained and man-portable. Potable power will, of course, be needed to energize and maintain this equipment in an unattended mode. Fuel cells offer the bestalternative for these power requirements, because of their high energy and power density. Unfortunately, there is no current fuel cell technology t ...

"The team of Visidyne, Inc. and Mission Research Corporation proposes to develop a high-fidelity, real-time Nuclear Optical Dynamic Digital Image Generator (NODDIG) to support the development and testing of algorithms for the mitigation of optical clutterin nuclear environments. The NODDIG concept is a software/hardware digital scene generator. It will complement and support infrared sensors under ...

"The primary objective of this proposed research is to develop a new detector that uses the wavelet transform for accurate, reliable and automatic detection of secondary phases such as Pg, Lg, and pPn. We propose to extend the semi-automatic waveletdetector of Tibuleac and Herrin (1999) to an automatic, multi-component detector for use on both single-component array data as well as three-componen ...
