Report No.: arXiv:2301.11247

Abstract: We have designed and implemented an experiment to measure the angular distributions and the energy spectra of the transition radiation X-rays emitted by fast electrons and positrons crossing different radiators. Our experiment was selected among the proposals of the 2021 Beamline for Schools contest, a competition for high-school students organized every year by CERN, and was performed at the DESY II Test Beam facility area TB21, using a high-purity beam of electrons or positrons with momenta in the range from $1$ to $6 ~GeV/c$. The measurements were performed using a $100~\mu m$ thick silicon pixel detector, with a pitch of $55~\mu m$. Our results are consistent with the expectations from the theoretical models describing the production of transition radiation in multilayer regular radiators.
