Abstract

An intense positron source, ¹⁸F, with a half life of 110 min has been developed for spin polarized positron beams. The radioactive ¹⁸F (ca. 30 GBq) is produced in 1 ml ¹⁸O-water target via the ¹⁸O(p,n)¹⁸F reaction with a 14 MeV proton beam at a current of 20 μA in the AVF cyclotron vault. An irradiated ¹⁸O-water is transferred to an experimental vault downstairs to be trapped and placed just in front of the moderator. The electrodeposition method was used to collect and fix ¹⁸F on a small spot from ¹⁸O-water. Recovery of ¹⁸F on the graphite cylinder of 5 mm is 69% and 35% for 3 mm cylinder, respectively.
