LumArray proposes in Phase I to demonstrate that its direct-write maskless-photolithography system, the ZP-150, is capable of performing aligned cuts in 1D-grids suitable for the 45 nm node, in addition to writing patterns of arbitrary geometry as required in custom ASICs and a wide range of other DoD and Aerospace applications. In Phase II LumArray will propose to make upgrades to its ZP-150 syst ...

The NNSA-sponsored development of the Dynamic Compression Sector (DCS), at the Advanced Photon Source at Argonne National Laboratory, will permit real-time X-ray measurements (diffraction, imaging, scattering) in dynamically compressed materials, and enable understanding of the dynamics of materials response to intense shock waves, which heretofore has not been possible. Such studies are critical ...

STR proposes to build Categories via Context-Driven Dimensionality Reduction (C2D2R), a novel, highly efficient, and scalable information processing pipeline for joint learning of categories of entities and relations, and document topics.C2D2R operates in three stages: shallow pre-processing of text inputs, context-driven dimensionality reduction, and joint category inference and labeling. Our sys ...

The project will develop a handheld instrument that detects, identifies, and categorizes radioactive sources based on gamma, thermal-, and fast-neutron signatures. Existing radioisotope identification devices (RIIDs) are typically biased toward gamma spectroscopy, and often use a simple, inefficient neutron counter. The recent development of Cs2LiYCl6:Ce (CLYC) has enabled neutron and gamma spectr ...

From 1993 to 2013, sixteen incidents involving highly enriched uranium associated with illegal activity has been reported to the IAEA.An implosion type of weapon would require roughly 25 kg of highly enriched uranium (HEU).One component in the layered defense against nuclear weapons is standoff detection of special nuclear materials, as HEU is material that can be easily deployed in a nuclear weap ...

A compact laser driver will allow photoconductive semiconductor switches to be used in small EMP simulator "building blocks" (EMPBB). Combined with a battery powered on-board pulsed power system, these EMPBBs will allow the construction of flexible EMP test facilities with nothing more than a single fiber optic timing connection to each EMPBB.

Diagnostics and instrumentation is needed to evaluate the effectiveness of the next generation of technology to defeat chemical and biological weapons.This proposal addresses the need for instrumentation to quantify the spatial and temporal evolution of fundamental physical and chemical processes, such as temperature and species identification and concentration, pertinent to the pyrolytic destruct ...

Certain lanthanide halides have significantly higher light output than NaI:Tl, the comparison standard for scintillators, plus other important properties, including fast decay times and excellent proportionality. Unfortunately, lanthanide halides grown by traditional melt processes have high production costs and limited availability. Crystals are usually limited to about 5 cm x 5 cm, right cylinde ...

It is proposed to develop a novel process for growth of high quality CZT crystals for nuclear detection applications. Currently the THM process is the technology of choice for production of high quality CZT crystals. This process, however, suffers from extremely low growth rates. The development effort proposed here will seek to increase the crystal growth rate by 5-10 times the current levels ...

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 ...
