ABSTRACT: In this STTR phase II, HYPRES and University of California San Diego team will demonstrate a small size, weight and power, wideband (2 MHz to 2 GHz) receiver prototype based on SQUID array technology. Our SQUID array designs are based on highly linear bi-SQUID and SQUID cells arranged into a 2-dimensional (2D) array. The 2D arrays are fabricated using high-temperature superconductor I ...

ABSTRACT: In this STTR Tech-X corporation in partnership with the University of Washington will improve a commercial plasma modeling tool, Nautilus, for simulating high-temperature multi-fluid plasmas for problems such as the field reversed configuration, dense plasma focus and the plasma opening switch. Semi-implicit algorithms will be implemented in Nautilus so that the speed of light and elec ...

ABSTRACT: Microscopy is a critical enabling technology for advancing our understanding of nature. Imaging nano-scale objects with light in the extreme ultraviolet (EUV) and soft x-ray regions of the spectrum has advantages over visible light for several reasons including: resolution, elemental specificity, and the ability to image internal structures. Coherent diffractive imaging (CDI) has been ...

ABSTRACT: ORBITEC will develop a new diagnostic to acquire simultaneous planes of velocity and temperature data at very high repetition rates. This diagnostic relies on a novel pulse burst laser system, a phosphor thermometry technique, and the mature PIV method. The work plan will involve developing and testing the laser, refining the integrated technique, and demonstrating it in a supersonic ...

ABSTRACT: A smaller transmitter package operating in C-band with greater power efficiency will pave the way for newer, compact weapons to utilize the expanded frequency range at C band. BENEFIT: Reduced payload weight, giving off less heat, with longer battery life.

We propose to develop a prototype of a novel spintronic spectrum analyzer using an array of nano-scale magnetic spin-torque detectors. The operation of the proposed spectrum analyzer is based on the recently discovered effects of spin-transfer torque and spin-diode effects in nano-scale magnetic multilayered elements, the fabrication of which became possible due to the recent advances in nano-fabr ...

The DF&NN team has significant experience in delivering Space Domain Awareness tools. These tools will be applied to 2 years of GEO ephemeris data of active satellites at DF&NN. The RDESB prototype will reduce the risk in rapidly discovering the behavioral patterns of potentially evasive and/or ambiguous active resident space objects. RDESB will detect non-Keplerian behavior in ephemeris data for ...

The goal of the proposed work is to provide the Air Force with a state-of-the-art model of the outer zone energetic charged particles, including data assimilation capabilities. The UCLA-developed Versatile Electron Radiation Belt (VERB) model will be optimized for various measurements obtained on various satellite orbits by different instruments. We will transfer VERB code to SSI, test and validat ...

Earths outer radiation belt, which consists of electrons with hundreds of keV to MeV energies, is a highly dynamic and driven environment.The large variations in electron flux, if unaccounted for, can cause satellites that travel through this complex region to experience anomalous behavior ranging from temporary satellite outages due to electrostatic discharge events in system electronics to poten ...

The objective of this proposal is to examine the feasibility of defining and measuring key dimensions of an urban system to include its essential functions and networks, and whether they can be modelled in a computational framework for assessing robustness and resilience of DUTs (and their tipping points) under conditions of volatility and stress. This proposal will conduct a comprehensive review ...
