This proposal addresses the problem of PCSS/laser trigger integration using a single monolithic laser diode array, thus simplifying the entire optical delivery network necessary for efficient operation of PCSSs. The proposal constitutes a logical continuation of Phase I effort where the main focus was on the detailed design of the PCSS/laser diode array (LDA) integrated architecture. In Phase II ...

Random numbers are essential for a growing number of modern applications. As computer speed and communications bandwidth have increased the potential for practical streaming cipher and large-scale Monte Carlo simulations have become technologically feasible. For these and other applications, ultrafast random number generators are essential. This is intuitively clear. Additionally, however, the ide ...

The objective of this Phase II proposal is to continue the development of a Photoconductive Semiconductor Switch (PCSS) with an integrated optical trigger that can switch at least 30 kV, 1 kA, 20 ns pulses with jitter 108 shots. Ness Engineering, Inc. (NEI) and Texas Tech University (TTU) propose to utilize wide bandgap materials to demonstrate lock-on switching and allow much less optical trigger ...

There is an unmet demand for ultra-low-power, ultra-compact and low-cost radios to address emerging sensing and communication needs for military and commercial applications such as IoT/IoE. To overcome the limitations in existing bulky and power hungry radios, we propose a disruptive solution by integration of a nano-scaled THz transceiver, on-chip antenna, and energy harvesting circuits in a form ...

Variational two-electron reduced-density-matrix (v2RDM) methods can provide a reference-independent description of the electronic structure of many-electron systems that naturally captures multireference correlation effects. These methods offer one of the few possible routes to performing the large-active-space computations that are necessary for the qualitative description of strongly-correlated ...

In response to the Army STTR Topic A14A-T015 solicitation for tunable high-power LWIR lasers for standoff detection applications, Pranalytica proposed to develop a compact, rugged and highly reliable wavelength tunable quantum cascade laser (QCL) module delivering over 5W of peak power and over 0.5W of average power in the spectral region spanning from 7 to 11m. The proposed approach is based on a ...

The modern warfighter faces the constant threat of endemic infections, multi-drug resistant bacteria and Biological Warfare Agents. In order to provide accurate front-line treatment that will curtail the overuse of antibiotics, a rapid and robust molecula

Next Dimension Technologies and Caltech will jointly develop a handheld detector to meet the Armys need for a field-based illicit drug identification system. The project will focus on the design and development of a dual-mode chemiresistive sensor array capable of detecting key drugs of interest, including synthetic cannabinoids and opioids. Novel sensing materials, with enhanced chemical sensit ...

This Phase I STTR project will develop a platform to demonstrate high-quality, multi-modal acquisition of neurophysiological signals, including EEG, heart rate/blood oxygenation via photoplethysmography (PPG), electrodermal (EDA) activity, temperature plus environmental factors such as ambient light and sound in a simple, wearable headband. The hardware will be coupled with the development of a cl ...

Using advanced ion optics that was developed by Pacific Northwest National Laboratory (PNNL), BaySpec will develop a prototype of portable mass spectrometer (less than 40 lb. and 300W) with continuous atmospheric pressure inlet that is fully capable of uninterrupted on-line sampling from an ambient environment. The continuous nature of the inlet ensures full compatibility with separation technique ...
