The highest available operating temperature for magnet wire is 240 degrees C. As electromagnetic performance is directly related to the density of winding turns times the operating current, the maximum operating temperature of magnet wire is the largest single constraint to advancements in high performance and high temperature electronics.

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 ...

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 ...

We propose to construct and test a prototype system capable of non-invasively probing the characteristics of material properties using acoustical waves through thermal conversion of a remote laser pulse. The advantages of proposed system as an inspection and identification technique are: 1) Non-contact: Sensor does not require contact with container 2) Stand-off: Sensor could be located many meter ...

The objective of this research is to develop beta versions of tools for automatically migrating radiation effects predicted in TCAD level tools to compact modeling tools. This transition will enable compact models that possess radiation effects to be quickly generated, which can then be used in circuit design activity. This approach is a substantial improvement over the current ad hoc approaches. ...

The atmospheric transport and dispersion (ATD) model requirements for describing the environmental conditions that are most likely to occur on any given day, called the "typical day", are very unique. The model requirements are unique because the typical day requirements for ATD must be both typical in representing the most likely occurring condition of each variable and be mass-balanced across t ...

Various procedures have been proposed for evaluation/mitigation of the potential for progressive collapse in the design and/or retrofit process. These range from passive procedures that evaluate the redundancy of structures to limit failure through redistribution of gravitation loads after key elements such as columns have been removed to complete nonlinear finite element analyses of buildings sub ...
