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 (12.8MeV, 45μA) of monoisotopic yttrium foils (0.64mm, direct water cooling) were performed to produce (89)Zr. The yields were 2200±200MBq (1h, n=13) and 6300±65MBq (3h, n=3).
