CPS-GAM Gamma Spectrometer

  • Introduction
  • Parameters

* Measurement time can be adjusted, and debris analysis is generally set at 600s with high efficiency

* Model was established by adopting single nuclide sources of K, Th and Ra, which met international standards

* High energy region characteristic spectral line is adopted, with small local interference, little interference between each nuclide and high spectral resolution

* The inverse matrix method is adopted to eliminate the influence between each nuclide peak, and the calculation results are accurate

* Provide fixed standard material for easy self-calibration

* The special sample box increases the detection area and the measurement results are more accurate




  • * Digitize 1024/2048 channels of analyzer
  • * Pulse mode and spectral line mode are freely interchanged
  • * Trapezoidal pulse forming, forming time: 2μS;
