"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, ...

The objective is to modify and test gas turbine engines presently installed in/on marine craft to demonstrate that by adapting technology used on street legal vehicles can be used to reduce the heat and noise levels in marine craft. Whether or not the IR15dB level or lower, and the above water acoustic/noise level to 60dB level or lower can be achieved, is a matter that can only be demostrated by ...

Science based assessments of the response of systems and material to hostile nuclear environments require detailed verified material response and failure criteria for confident results. Consequently there is a need for the development of experimentaltechniques to measure low pressure equation of state parameters accurately and economically using radiation simulators. The development of a soft x- ...

This proposed work will generate a targeted phosphate ester hydrolysis catalyst for agent denial. This catalyst will be targeted by conjugation to single stranded DNA. Characteristics of the catalyst will be determined, including ruggedness, targeting selectivity, and potential methods for deployment.

"This proposal describes a unique concept for a low light, compact image intensification system that provides multi-spectral input and output capability in contrast to the current broadband input/green output capability of conventional image intensificationdevices. Present image intensifiers use a broadband photocathode sensitive to visible and near-IR optical radiation and provide green imagery ...

Present reflex triode (RT) design performance is limited by debris shield response. The shield designs were derived empirically to satisfy specific experiment requirements. Optimizing the RT design will double target dose. Debris shield deformation definesthe closest permissible location of the test object and therefore determines the maximum dose achievable. The deformation of the debris shield c ...

"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 ...

"Our Phase I study proved the feasibility of using monofilament carbon tow and thin resistant wire in a glove system to provide an adequate heat source to keep a soldier's hands comfortable in extreme cold temperatures while retaining hand dexterity andtactility. Our objectives during Phase II are to (1) incorporate our heat generation process into a super thin, non-melting, flame-rerardant materi ...

Special Operations forces (SOF) operate in all weather conditions. It has identified a need for a micro-cooling system that can be vehicle mounted and man-portable, as well as provide a capability to cool vehicle mounted communications and electronics equipment. To meet the needs of SOF the system must be small, lightweight, quiet, low power, and gasless. We propose a compact micro-cooling system ...

The measurement of the variation of fluence from a Plasma Radiating Source (PRS) with polar angle is critical to the definition of the stimuli acting on an effects experiment using PRS diagnostics because in general experiments and diagnostics view thesource from different angles. The polar angle fluence distribution is controlled by the opacity of the pinch, which is a sensitive function of pinc ...
