DESCRIPTION

  • HPGe detectors with extended energy range GCDX-OS are different from GCDX by its shape. It is still allowing to go lower in energy range down to 3 keV and thin contact structure of the HPGe detector guarantee low energy photon transition to the HPGe crystal and its registration.
  • Input window made of Beryllium or Carbon fiber of the detector is integrated into the end cap of the detector by using high-tech vacuum-tight materials.
  • GCDX-OS HPGe detectors are showing way better performance, such as resolution improvement, if you consider energy range from 100 keV to 662 keV. This is vitally important for those applications where radionuclides with lower energies are required to measure and analyze.
  • Over-square shape HPGe crystals of the GCDX-OS detectors provide better efficiency while measuring relatively compact samples like bottles, vials, petri dishes, etc.
  • Increase of efficiency is observed due to the fact that HPGe crystal is having similar volume to GCD and GCDX detector but larger diameter in relationship to its height. Therefore, relative intensity and efficiency are higher in energy range 1.5-2 MeV.
