Transition radiation measurements with a Si and a GaAs pixel sensor on a Timepix3 chip

Growing energies of particles at modern or planned particle accelerator experiments as well as cosmic rayexperiments require particle identification at gamma-factors (𝛾) of up to∼105. At present there are no detectorscapable of identifying charged particles with reliable efficiency in this range...
