HPIC Meeting - Austin Barry Wilson Key Account Manager South West ORTEC 1
Who is ORTEC? Parent Company is AMETEK NYSE ticker AME Subsidiary Name is Advanced Measurement Technologies Inc. Brand Names are ORTEC, Princeton Applied Research and Signal Recovery ORTEC was founded in 1960 by Researchers from ORNL to build commercial charged particle detectors made of semi-conductor materials (silicon). Currently about 280 employees world-wide. Factory in Oak Ridge 2
Key Technology: HPGe Detectors ORTEC is a world leader in nuclear instrumentation, including both growing HPGe crystals and fabricating detectors. ORTEC has significant experience in large scale production of HPGe detectors for a variety of projects. 3
Key Technology: DSP Hardware ORTEC was first to commercialize Digital Signal Processing (DSP) technology in an integrated gamma ray spectrometer. ORTEC holds nine separate patents in the area of DSP based MCA technology alone. 4
Key Technology: Coolers Electromechanical cooling system for Fixed/Installed Applications Portable Cooling System for the Field Since 1984, ORTEC has delivered more LN2 free HPGe cooling systems than any company in the world. Patented Low Frequency Rejection digital filtering makes it work. Hundreds of reliable systems delivered per year. 5
Key Technology: Software Found Industrial(1) Suspect NORM(1) Found Nuclear Uranium High degree of collaboration with national laboratories for state of the art analysis methods. Broad-based software group continually working on an equally broad range of new products (both nuclear and otherwise) ensures we keep up with technology. 6
Radiological/Nuclear Terrorism Preventing the Spread of Illicit Nuclear Materials 7
Potential Points of Entry 8
The Cost of False Alarms False Positives (nuisance alarms) 90% of innocent alarms at airports are due to medical isotopes in the bodies of travellers In cargo/freight, the major problem is caused by natural emitters. Suspending operations in just one terminal for just one hour could cost close to $500,000, said Bethann Rooney, Port Authority s Manager of Port Security, New York Harbor. False Negatives Report cargo is clean when in fact a source is hidden inside 9
