Abstract

The conditions and effective factors of ~(18)F~-which produced by ~(18)O(p,n) ~(18)F with TR19 cyclotron are investigated.The results show that the higher abundance of target water,the higher yield of ~(18)F~-when the proton beam current is 10～35 μA and the irradiation time is 20～60 min,the yield of ~(18)F~-is increased with the increasing of the proton beam current and irradiation time.Thus,the abundance of target water,proton beam current,irradiation time are the main factors affecting the yield of ~(18)F~-.
