Fluorine-18, which is a widely-used positron emitter, has been produced regularly since 2015. In addition, research on the production of generator radioisotopes has been performed using this cyclotron. A generator means a device used to extract the positron-emitting daughter radioisotope from a source of the decaying parent radioisotope such as Ti-44 and Ge-68. In this research, gold-coated and natural Sc targets were proton-irradiated in order to produce Ti-44. Gamma spectra of irradiated targets were measured to confirm the production of Ti-44.
