A solid target system was developed for a PET cyclotron. The system is compatible with many different target materials in the form of foils and electroplated/sputtered targets which makes it useful for production of a wide variety of different PET radionuclides. The target material is manually loaded into the system. Remote handling of irradiated target material is managed with a pneumatic piston and a vacuum technique which allows the targets to be dropped into a shielded transport container. To test the target performance, proton irradiations (12.8 MeV, 45 mu A) of monoisotopic yttrium foils (0.64 mm, direct water cooling) were performed to produce Zr-89. The yields were 2200 +/- 200 MBq (1 h, n=13) and 6300 +/- 65 MBq (3 h, n=3).
