The recirculating electron linac S-DALINAC* provides beams with currents up to 20 µA and energies up to 130 MeV. It is planned to extend the beam diagnostics by adding multiple emittance measurement systems in order to investigate the emittance evolution along the beamline. The emittance measurement is based on the quadrupole scan technique and utilizes the existing quadrupoles and newly built optical transition radiation targets. As the targets are heated by the beam and destruction must be avoided, simulations of the thermal behaviour of the target were conducted. In particular, the dependence of the target temperature on the target design, but also variable parameters as beam spot size and current were investigated. This contribution will present these parameter studies.
