The Compressed Baryonic Matter (CBM) experiment will access a wide range of physics observables for heavy-ion collisions in the region of highest net-baryon densities. One of the core topics of its physics program are the measurement of rare thermal dilepton channels. These EM probes have a very low cross section and therefore need very high statistics and a powerful particle identification. The combination of the Ring-Imaging Cherenkov Detector (RICH) and the Transition Radiation Detector (TRD) provide a good electron identification over the whole momentum range and especially for the study of thermal radiation into dielectrons at intermediate masses the electron identification capabilities of the TRD are crucial. The measurement of thermal dileptons in the intermediate mass range and at different energies of the CBM energy range would provide a better understanding of the excitation function and therefore could give insights about potential phase transitions in CBM’s region of the QCD phase diagram. This contribution will present the newest simulations at different collision energies of spectra of dielectrons and the extraction of the fireball parameters from dielectrons at intermediate masses.
