Abstract
2.2 GBq of 18F (half-life 110 min) was effectively deposited on a graphite electrode of diameter 3 or 5 mm. The fraction of the electro-deposited 18F was as high as 97% of the total 18F produced in the solution. The fraction of the positrons emitted out of the electrode was 44% of the total β+. Thus, as much as 36% of the β+ from the produced 18F is available for the source of slow positron beams.
