Improved Models and Tools for Prediction of Radiation Effects on Space Electronics in Wide Temperature Range, Phase IIdata.nasa.gov | Last Updated 2020-01-29T02:04:47.000Z
All NASA exploration systems operate in the extreme environments of space and require reliable electronics capable of handling a wide temperature range (-180ºC to +130ºC) and high radiation levels. To design low-temperature radiation-hardened (rad-hard) electronics and predict circuit and system characteristics, such as error rates, modeling tools are required at multiple levels. To determine the electrical responses of transistors and circuits to radiation events, physics-based Technology Computer Aided Design (TCAD) and mixed-level tools are required. This project will provide models and tools that will improve capabilities for prediction of technology-dependent responses to radiation in wide temperature range, which will lead to better design of rad-hard electronics, better anticipation of design margins, and reduction of testing cost and time. Future NASA missions will use nanometer-scale electronic technologies which call for a shift in how radiation effects in such devices and circuits are viewed. Nano-scale electronic device responses are strongly related to the microstructure of the radiation event. This requires a more detailed physics-based modeling approach, which will provide information for higher-level engineering models used in integrated circuit (IC) and system design. Hence, the proposed innovation: detailed high-energy-physics-based simulations of radiation events (using MRED/Geant4 software from Vanderbilt University) efficiently integrated with advanced device/circuit response computations by CFDRC NanoTCAD three-dimensional (3D) mixed-level simulator. This will also enable a large number of statistically meaningful runs on a massively parallel supercomputing cluster. The extreme low temperature physics models combined with radiation effects will be validated with the help of consultant, Dr. John Cressler (Georgia Tech), in collaboration with the NASA Extreme Environment Electronics program, and serving the NASA RHESE Program (led by NASA-MSFC).

<p>We want to look at the concept of combining small, passive windows with replaceable cameras to improve viewing capabilities for habitable modules of future spacecraft. A more modular concept than currently used for spacecraft windows, this concept would reduce the overall window square footage for a vehicle or habitat, yet increase the viewing capabilities around it, and be available for both passive and electronic (video camera, IR sensors, etc) methods. This project would evaluate configurations of small portal windows with internally placed imaging sensors, pointed in various directions, and integrated views of near real-time video.<p/><p>Windows in habitable modules represent significant design and operations impacts to future spacecraft, yet viewing requirements, both electronic and passive, continue to mature. With longer missions over greater distances, it becomes harder to accommodate both size and modularity of viewing. The Hybrid Window Portal would allow easier design, more locations for direct viewing, and easier maintenance and represent less of an impact to a vehicle's structural integrity than traditional windows, and applies to aluminum, composite and inflatable structures. This project intends to build on an on-going IR&D effort and a 2011 ICA investigation of virtual window technology, and will explore options to provide adequate viewing and sensing through arrangements of multiple, small portals that can accommodate cameras and sensors. Smaller portals accommodate more cameras and sensors than ever before, and offer different pointing directions so optimum viewing angles can be selected, while an integrated view (Mosaic Video) provides perspective. </p>
High Temperature, Radiation Hard Electronics Architecture for a Chemical Sensor Suite for Venus Atmospheric Measurements, Phase Idata.nasa.gov | Last Updated 2020-01-29T04:59:55.000Z
Makel Engineering, Inc. proposes to develop a high temperature, radiation hard electronics sensing architecture for a high temperature chemical sensor array suitable for measuring key chemical species in the Venus atmosphere. The previously developed Venus Microsensor Chemical Array (VMCA) consists of sensing elements which can operate in a 500 C environment, but which currently rely on silicon based electronics for signal acquisition, control and data transmission, which requires active cooling for a Venus mission deployment. NASA GRC has demonstrated simple SiC electronic circuits, such as differential amplifiers and logic gates that were packaged and operated for a world-record of thousands of hours at 500 C. Ongoing work at NASA, universities, and industry is increasing the complexity and capability of SiC devices. This proposal aims to develop electronics designs and architecture to enable NASA's high temperature SiC electronics to be applied to the VCMA to form a science instrument suitable for a future Venus mission. Phase I will develop innovative designs using near term SiC components to provide transduction and signal processing needed to operate the VMCA without active cooling. Phase I designs will be demonstrated in hardware using silicon versions of electronics components which are achievable in SiC. This process is the key first step in applying emerging development of SiC electronics to a harsh environment chemical sensing need. Phase II will focus on implementation of the SiC electronics design utilizing the best available SiC components.

This measure tracks the average number of cases in the Office of the Child Attorney open during each quarter. Each case represents a court proceeding involving child abuse or neglect. Children lack the capacity to speak for themselves in court proceedings and need someone else to speak and act on their behalf. The Office of the Child Attorney exists to ensure that children have access to adequate and effective child advocate attorneys.

This area of the website provides information on three of the safety programs established by FMCSA to support this mission. The three programs covered by this area include reviews, roadside inspections of commercial vehicles and drivers, and traffic enforcement stops of CMVs operating in an unsafe manner. Each program is implemented in conjunction with the states and devoted to improving motor carrier safety by reducing the number and severity of crashes involving large trucks and buses.
