  2. Outline • Background: ASPECT Aircraft & Program • ASPECT GEM Purpose and Goal • GEM Team • Radiation DetectionTechnology • Example Test Runs • Future Work

  3. Program ASPECTAIRCRAFT PLATFORM • AeroCommander Platform • Base of Operation: Waxahachie, Texas • IFR/GPS Equipped • High Quality Filtered Power • STC Camera Holes in the floor • Crew: Two Pilots, One Operator, All Commercial/ATP Rated • Speeds: • Data Collection at 100 kts • Cruise at 180 – 200 kts • Range/Aloft Time: • Range 1,100 NM • Aloft Time 4 – 6 hours • Service Altitude: • Data Collection at 200 to 2,000 ft AGL • Cruise at 20,000 ft (with Supplemental Oxygen) • Ground Needs – Standard FBO

  4. ASPECTAirborne Spectral Photometric Environmental Collection Technology • The primary mission of ASPECT is to provide information to the first responder in a form that is timely, useful, and compatible with existing infrastructures. • ASPECT can provide infrared & photographic images with geospatial chemical and radiologicalinformation. Methanol plume

  5. ASPECT OPERATIONAL REQUIREMENTS • Rapid Response —Wheels-up within one hour • Direct Integration into the Local Incident Commander • Standoff Detection of Chemical Plumes and Gamma Contamination • Automatic Processing • Real (or Near Real) Time Collection of Data • Aerial Photography Capability • Basic Data Communication

  13. Radiation Detection Technology • Radiation Solutions RS-500 • 3 2”x4”x16” Sodium Iodide • 1 3”x3” Lanthanum Bromide Detectors Advance Digital Spectrometers PMT

  14. Top Ten Features • Digital Design – More stable, less drift, higher count rates, “cleaner” spectra i.e. better data. • No Internal or External Test Sources – No radioactive material transport issues. No lost or misplaced sources. • Self Diagnostic with Auto System Validation – An Advanced design enables a more self contained system requiring less operator interaction. Individual detector raw data is archived in the system 4. Multi-Peak U, K, Th Auto-Stabilization – Stabilizes in all areas, Faster, 3 min vs 30 min.

  15. Top Ten Features 5. Individual Crystal ADC’s& Processing – The high speed sampling of pulses allows for pulse analysis and DSP processing. Resulting in improved pulse pile-up rejection, zero dead time & a higher throughput. • Wide Dynamic Range – From low level to 1,000,000+ cps for each crystal. • Individual Crystal Linearization with proper Poisson noise characteristics

  16. Top Ten Features • Expandable Unlimited number of crystals (limited only by weight considerations) • Wide range of Connectivity options – RS232 serial, TCPIP and USB. Utilizing data compression that allows for full spectral data transfer every second over wireless devices. • Modern Compact Design – Strong & Efficient Case, Modular, Meet FAA requirements

  17. ASPECT GEM Project Purpose: To improve the US EPA airborne gamma-screening and mapping capability of ground-based gamma contamination following a wide-area radiological dispersal device (RDD) or improvised nuclear detonation (IND) attack. Goal: To develop the most advanced gamma-radiation detection capability mountable within an Aero Command 680 FL airframe. www.epaosc.net/aspectgem

  18. EPA Homeland Security ASPECT GEM project directly supports the EPA Office of Homeland Security focal area that directs the agency to: ”Develop appropriate/effective technologies to lessen the time frame for characterization and decontamination of contaminated widespread and populated areas following an RDD.”
