A source for polarized positron beams at the Continuous Electron BeamAccelerator Facility (CEBAF) at Jefferson Lab is being designed. The PolarizedElectrons for Polarized Positrons (PEPPo) concept is used to produce polarizede$^+$e$^-$-pairs from the bremsstrahlung radiation of a longitudinallypolarized electron beam interacting within a high-$Z$ conversion target. Thescheme under consideration includes a 4 mm thick tungsten target that absorbs17 kW deposited by a 1 mA continuous-wave electron beam with an energy of 120MeV. The concept of a rotating tungsten rim mounted on a water-cooled copperdisk was explored. The results of ANSYS thermal and mechanical analyses arediscussed together with FLUKA evaluations of the radiation damages.
