"Nach 40 Jahren γ-Spektrometrie"
Endlich eine komplette Analyse hochauflösender HPGe-Spektren
Eine neue Generation in der Analyse von γ-Spektren
Januar 25, 2019
Eine neue extrem leitungsfähige Methode zur Analyse hochauflösender γ-Spektren:
  • A spectrum-wide shape is formed for each nuclide with activity adjusted at each iteration
  • For all nuclides the full-spectrum shapes are summed and automatically repeated for best fit
  • VRF is visually-driven for reporting, graphing and specialized analysis
  • Detector energy, resolution and efficiency calibrations best fitting by up to 6-order Pade
  • High sensitive identification of minor peaks that are masked by larger overlapping peaks
  • Automatic activity correction for decay during acquisition & collection and since collection
  • Automatic random & true-coincidence summing and single, double and x-ray escape corrections
  • Three different attenuation groups are selectable including low-energy peak-tail fitting
  • Applicable to activation analysis for prompt and delayed neutrons
  • Implemented calculation of isotopics ratios, e.g. for U-235/U238 or Pu-240/Pu-239
  • Editable libraries (txt-files) for 1180 isotopes (3840 in preparation), selectable decay sequences (chains), all x-rays, 183 neutron activated nuclides and customizable groups of isotopes
