Simulation of gas properties in various mixtures for high resolution position sensitive gas detectors
A simulation software has been developed to predict the spatial resolution of a gas detector for x-ray applications, including the range of photoelectrons, fluorescence photons and Auger electrons as well as the broadening by diffusion in the gas mixture. Gas properties (drift velocity, characteristic energy, diffusion) are evaluated over a wide range of the reduced field (0–2) kV/(cm∗ bar) by a Monte Carlo approach. Possible mixtures to be simulated are (Ar, Kr or Xe) + CH4 in any proportion. Results of the properties for common gas mixtures as measured are shown to be in good agreement with the calculated results.
