Space Radiation Detector with Spherical Geometry

This technology enables in-situ studies of the impact of Galactic Cosmic Radiation ions on Earth and in space.

NASA’s Glenn Research Center has developed and patented the Compact Full-Field Ion Detector System (CFIDS), a radiation particle detection system that provides information on the kinetic energies, directions, and electric charges of subatomic particles. The integrated package consists of a spherical Cherenkov detector, a compact detector stack, and low-noise, large-area detectors based on silicon carbide. The detectors and configuration can be modified to suit specific applications. The technology is an improvement over more conventional gas ionization detectors because the higher density of the solid media provides higher sensitivity to radiation. Originally developed to measure the properties of cosmic rays in outer space, the technology could be adapted for use on Earth for radiation dosimetry aboard high-altitude aircraft and in proton radiation therapy for cancer treatment.

Method of Mapping Anomalies in Homogenous Material

This technology combines the SansEC circuit with a magnetic field reader to produce a spectroscopy readout.

This innovation builds off of NASA Langley Research Center’s SansEC sensing system. SansEC is an open-circuit, resonant sensor that needs no electrical connections (thus the name SansEC or “without electrical connection”). This technology combines the SansEC circuit with a magnetic field reader to allow for detection of magnetic or electric field changes to produce a spectroscopy readout.

Nick Krotkov, Atmospheric Scientist, Goddard Space Flight Center, Greenbelt, MD

Using data from NASA’s Earth Observing System Aura satellite, launched in 2004, a team led by Michigan Technological University created a global map of volcanic emissions. Scientist Nick Krotkov will use the information to refine climate models and better understand the human and environmental health risks of erupted gases like sulfur dioxide.

AutoSurvey™ Software System

The U.S. Navy has developed a software system that optimizes the collection of data for hydrographic surveys. The autonomous survey system, called AutoSurvery, is an easy-to-implement, real-time adaptive software system for the collection of swath-type data that minimizes survey time while maintaining data quality and ensuring the desired coverage.

Authenticated Sensor Interface Device

Researchers at the Savannah River National Laboratory (SRNL) have developed a device to read data, encrypt the information, and distribute it electronically to multiple locations, providing a one-way data pathway that segregates each destination to prevent cross-party data manipulation. Previous “data diode” devices employ computer-based communication channels such as fiber-connected data cards between the sender and receiver. No integrated data authentication is performed, and data is sensitive to external attack and manipulation.

Photo-Acoustic Chemical Detector

This technology could be used for the detection of explosives and hazardous or toxic chemicals.

NASA's Langley Research Center has developed a photo-acoustic sensing-based laser vibrometer for the measurement of ambient chemical species. The technology allows for detection of sub-part-per-billion (ppb) levels of ambient trace gases and chemical species, with an order of magnitude more sensitivity than similar technologies. Among other applications, the technology could be used for the detection of explosives and hazardous or toxic chemicals.
