Measuring polarization in the X-ray range: New simulation method for gaseous detectors

In this work, we suggest Geant4 as a useful toolkit to simulate the photoelectric interaction of linearly polarized X-rays. In particular, we have developed a new calculation of the final state, properly taking into account the direction of the photo-electron. We simulate two experimental setups found in the literature and show that the simulation results obtained are in agreement with the experimental data.
