Parameterization models for X-ray transition radiation in the GEANT4 package Original Research Article

We discuss an implementation of parameterization models provided by the GEANT4 package for the description of the X-ray transition radiation (XTR) produced by a relativistic charged particle in a multi layered medium. The implementation allows us to calculate the number of XTR photons, their energy and angular spectra in a number of XTR radiators of practical interest. Comparison of simulation with experimental data from gaseous detectors is presented.
