14Top Ten FeaturesDigital 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 system4. Multi-Peak U, K, Th Auto-Stabilization – Stabilizes in all areas, Faster, 3 min vs 30 min.
15Top 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
16Top 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
17ASPECT GEM ProjectPurpose: 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.
18EPA Homeland SecurityASPECT 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.”

20ASPECT Open Houses March ’08: Cincinnati, OH July ’08: Las Vegas, NV April, ’09: DCJune, ’09: Albany, NYSummer ’09: WPAFBThese events improve the agency’s Homeland Security response capabilities by:1. Strengthening EPA intra-organizational and interagency relationships associated with emergency response functions,2. Increasing awareness of the agency’s national assets available to the regions, surrounding states, and response communities of the airborne chemical and radiological detection capabilities, and3. Serving as a forum to provide unique “hands-on” access to the agency’s latest technology developed for large-scale response and recovery applications.
21Modeling vs. Measurements EPA airborne and ground-based radiation detection technologies will provide long-term environmental measurement data.21

28Steam Separator Replacement Old Radiation Detection Capability Separator constantly moved during the data collection process.Image processed and transmitted via on-board satellite communications system to Command Center five minutes after last pass.Can send images to secure FTP and Blackberry.(8 passes, 50 minutes, 500 ft, 110 knots)
40Future Work Calibration Cross calibrate ASPECT GEM with DOE Aircraft Background (April 2009)Exposure Rate Calibration (RERT, July 2009)Activity Calibration (July, 2009)Cross calibrate ASPECT GEM with DOEAccelerated data exchange products (e.q. real-time contour mapping)Communicating uncertainties with mapsDetermine Minimum Detectable Activity for various operating conditions, andCreate or improve similar ground-based systems to be consistent with ASPECT GEM capabilities
