Performance Characteristics.

  • Energy detection range 20 KeV to 3 MeV
  • Detector Volume: 16.8 Liters downwards-looking, 4.2 Liters upwards
  • 256 / 512 / 1024 channels
  • Output is fully linearized, and the Poisson Distribution is not affected
  • Individual detector processing
  • Real-time stabilization on natural radioactive elements
  • Extremely wide dynamic range: up to 250,000 cps per detector
  • Insignificant Dead Time
  • Individual detector Acquisition and Live time is provided
  • Data acquisition is accomplished via Ethernet, which eliminates bandwidth problems and permits remote monitoring and troubleshooting
  • Internal Data Storage for use in Stand-alone mode
  • Selectable sampling rates
  • Elevated level of self-diagnostics
  • Automatic HV calibration and linearization based on natural radioactive elements (radioactive sources are NOT required). This permits field replacement of NaI(TI) detectors and/or photomultiplier tubes
  • GPS connectivity & synchronization
  • Input power: 10 to 35 VDC Cosmic Radiation recorded in the last channel for data processing
