This program seeks to develop and demonstrate, in severe mechanical shock environments, a new state-of-the-art data recorder for environmental measurements of warhead systems. The developed DSR data record will include 4 internal channels for measuring acceleration, weapon case strain, or pressure and 6 external input digital channels for other user defined measurements. High sampling rates will ...

In this project, we propose to identify and examine solution growth approaches for engineering perovskite single crystal for gamma spectrometry in a hand-held sensor format. We will demonstrate that the solution growth approach is able to produce perovskite single crystal in sufficient volume and quality to yield a detector crystal whose utilization presents no inherent environmental, health, or s ...

ESTABLISH DESIGN CRITERIA FOR, AN OPTICAL PROBE TO MEASURE THE DUST LOFTED BY THE SHOCK WAVE DURING A NUCLEAR BLAST WAVE SIMULATION. DUST DENSITY IS DETERMINED FROM THE REDUCTION IN INTENSITY OF LIGHT PROJECTED OVER AN INTERROGATION PATH TRANSVERSE TO THE FLOW. USE OF A SIMPLE LIGHT SOURCE AND DETECTOR WITH FIBER OPTIC TRANSMISSION LINES PRODUCES AN INEXPENSIVE RUGGED INSTRUMENT WHICH CAN BE DEPLO ...

The Radionuclide Aerosol Sampler and Analyzer (RASA) is a completely automated monitoring system that detects airborne radioactive particles and is one of the detection systems used in the U.S. and global International Monitoring System (IMS) of the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO) to detect nuclear detonations. Mainstream proposes develop a high-efficiency cyclone separa ...

The Inverse Free Electron Laser (IFEL) is a leading contender to demonstrate high gradient, high repetition rate laser acceleration for the next generation of small footprint, high energy (>200 MeV) accelerators for military applications. In the IFEL energy is transferred from a high power laser to an electron beam as they co-propagate through a magnetic undulator. The rapid development of laser t ...

The Defense Threat Reduction Agency, DTRA, currently uses technologies capable of detecting IEDs using airborne sensors that are demonstrated as reliable. These systems are only used for detection purposes and are not capable of neutralizing the IED. Due to IEDs being located in remote, dangerous, and hostile locations, there is high casualty risk for personnel to manually neutralize the target by ...

Accurate blast simulations based on first-principles, 3-D hydro-codes require hours on notebook PCs. Graphical processing units (GPUs) offer the potential of drastic reductions in run-times. Typical computational fluid dynamics codes perform of the order of 10-100 operations per memory fetch and store. In order to harness the potential of graphical processing units (GPUs), near-perfect streaming ( ...

The problems addressed by this proposal are related to the need for fast running models (FRMs) that predict damage imparted to structural components composed of UHPC materials, particularly slabs, by munitions related to their penetration and detonation. These FRMs are also to provide the resulting residual capacity of the component and account for the effects of multiple strikes. The FRMs need ...

State of the art Radiation Hardened by Design (RHBD) techniques must scale down in feature size for radiation effects in 45 nm processes, and also scale up in complexity to support radiation fault analysis of VLSI circuits. Recent access to commercial 45 nm CMOS Silicon-on-Insulator (SOI) technologies has increased the interest in this technology for rad-hard electronic applications due to the in ...

While current Software and Systems Engineering (SSE) methodologies provide a viable means for technically trained professionals to address HSI concerns throughout the system lifecycle, they tend to be inadequate for non-technical users. To overcome this limitation, the proposed effort is concerned with developing and integrating a set of HSI templates with an existing SSE tool and thereby refining ...
