This document describes the technical design and the performance of the Transition Radiation Detector (TRD) of the Compressed Baryonic Matter (CBM) experiment at FAIR. The main task of the TRD is to identify electrons above momenta of 1 GeV/c and thus to extend the electron identification capabilities of the Ring Image CHerenkov (RICH) detector above momenta of p ~ 5 GeV/c. This identification has to be achieved with a pion suppression factor of about 20 at 90% electron efficiency, in order to allow for a measurement of dielectrons in the mass range from below the rho and omega masses to beyond the J/psi mass with a good signal-to-background ratio. Due to its ca...
