It is well known that satellite communications and radar signals propagating in the natural ionosphere can be disturbed. It has also been widely reported that the ionosphere is subject to even greater disturbances following nuclear detonations. Hence the design of robust satellite communications and radar systems must take into account the effects of ionospheric disturbances. Radar and communic ...

Orora Design Technologies, Inc. proposes to develop an innovative computer-aided design (CAD) based methodology and enabling tools for rapid radiation-hardened prototyping and migration of military satellite microelectronics. A key innovative tool to be explored is automated generation and validation of behavioral models for complex analog, digital and mixed-signal circuits, including radiation e ...

The goal of this research is to develop electronic design automation (EDA) tools to automate the following three major radiation-hardened-by-design (RHBD) tasks: (1) The capture of RHBD design constraints and design rules for sub-90nm mixed-signal designs in an industry-standard EDA data base, (2) Checking and verifying if a given sub-90nm mixed-signal design satisfies all the RBHD design const ...

While many applications may have access to harvestable energy in the form of solar radiation (or other ambient light), wind, environmental vibration, or wave motion, not all do. In this proposal, RMD targets the most challenging applications, sensors that must operate for many months or years and which have undependable or no access to environmental energy. These sensors need a self contained, com ...

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 ...

State of the art Radiation Hardened by Design (RHBD) techniques must scale down in feature size for radiation effects in 45 nm processes, and also scale up in complexity to support radiation fault analysis of VLSI circuits. Recent access to commercial 45 nm CMOS Silicon-on-Insulator (SOI) technologies has increased the interest in this technology for rad-hard electronic applications due to the in ...

The proposed Phase II effort investigates innovative finite element formulations, alternative structural modeling procedures and modern parallel computational strategies to improve the computational performance of high fidelity simulation software for modeling the progressive collapse behavior of blast damaged buildings. Its goal is to reduce the time required to compute and visualize high fideli ...

We propose a new active optical method to measure time-domain waveform of THz pulse in the vicinity of the target in an omni-directional manner. This method utilizes the THz radiation-enhanced-emission-of-fluorescence from laser-induced air plasma to detect the THz field, which enables the standoff sensing for low volatility chemicals using THz spectroscopy. We have demonstrated its capability of ...

Three nuclides are especially useful in detecting thermalized neutrons: helium-3, lithium-6 , and boron-10. Since current demand will deplete reserves of helium-3 in roughly two years, there is a large desire to develop detectors that have the capacity to replace helium-3 tubes. In this proposal we spell out our plan to adapt Neotron''s already developed fission neutron detector into a high effic ...
