The injector of the TOP Linac (Oncological Therapy with Protons), under development by ENEA and ISS consists in a 7 MeV, 425 MHz RFQ+DTL (AccSys Model PL-7). It is actually in operation at ENEA-Frascati laboratories for the production of the positron-emitting radionuclide F18 for PET analyses by an intense proton beam (8 - 10 mA, 50 - 100 μs, 30 - 100 Hz). At the exit of the injector, the beam is guided through a magnetic channel to a target composed by a thin chamber (0.35 mm thick and 1 inch diameter) containing water enriched with O18. Two techniques aimed to flatten the proton beam distribution and so optimize the radioisotope production are compared: a spot scanning system and the use of a non-linear magnet system including octupoles. In the paper the details of the beam dynamic study and the first measurements results are presented.
