Simulation of the response of the IG11 4pigamma ionization chamber using GEANT Monte Carlo code
The response of the Centronic IG11 4pigamma ionization chamber filled with argon at 2 MPa pressure has been calculated by means of the GEANT Monte Carlo code and compared with experimental results in the range of photon energies from 40 keV to 2 MeV. The effect of density variations or thickness of the main components on the sensitivity have been investigated as well as source displacements. The sensitivity to electrons has been evaluated.
