In Phase I of this effort we analyzed the structural response of a BLU 109 during typical penetration events. Based on these finite element results, we proposed and demsonstrated a simple robust concept for a passive penetrator sensor that identifies the material being penetrated and also correlates strongly with its underground trajectory. Such a sensor would obviously provide valuable informatio ...

Orora Design Technologies proposes to develop electronic design automation (EDA) tools employing minimally invasive circuit design-based methods to mitigate single event effects (SEEs) for next generation Ultra-DSM CMOS (

Analysis of nuclear material samples in the field has many advantages over laboratory analysis. Laboratory analyses can be slow, involve increased expense, lead to additional waste generation and disposal problems, and may introduce errors due to sample degradation or mishandling. In situ analysis mitigates all of these problems. The specific aim of this project is the development of a truly por ...

A new type of compact induction accelerator currently under development at the Lawrence Livermore National Laboratory (LLNL) promises to increase the average accelerating gradient by at least an order of magnitude over that of existing induction machines. The machine is based on the use of high gradient vacuum insulators and advanced dielectric materials and switches. The system, called the Diel ...

Predicting the response of building components to internal detonations is more complex than the corresponding task for external loads because of the more complex loading waveforms which include multiple reflections in the shock phase followed by a long duration pseudostatic loading that depends upon room venting. Add the possibility of additional impulsive loading from primary debris. We propose t ...

"To operate sensors to verify future arms control agreements, inspectors will need a portable power source. The power source must be rugged, lightweight, reliable, adaptable to a variety of different sensor applications with different current/voltagerequirements, and simple to refuel in the field. We propose to develop a polymer electrolyte membrane (PEM) fuel cell that is ideal for arms control ...

"Now that reliable, robust, commercial proton exchange membrane fuel cells (PEMFCs) are available, the problem has shifted to fuel storage. PEMFCs function most efficiently (>50%) when supplied with pure hydrogen. Unfortunately, storing large quantitiesof hydrogen in a compact, lightweight form has proven to be very difficult. Most of the hydrogen storage methods that have been developed for fu ...
