Target systems for the production of positron emitting radioisotopes used for medical research with positron emission tomography (PET) are under development for a 3 MV electrostatic tandem accelerator (NEC 9SDH-2). This machine is intended primarily for the continuous production of short lived tracers labeled with or for determining regional cerebral blood flow in humans. Simple gas, liquid, and solid target systems are presented for the production of (yield at saturation 13 mCi/μA), fluoride (aq.) (12 mCi/μA), fluoride (aq.) (21 mCi/μA), in graphite (25 mCi/μA), and Current limitations on single window targets for each production are discussed.
