Description
Fluorine-18 produced by the 18O(p,n)18F reaction on 18O-water has proved to be highly useful as a source for a slow positron beam. About 70 GBq of 18F is produced routinely by an ultra-compact cyclotron. The 18F formed in H218O target is sent through a fine pipe to the site of positron slowing-down, fixed on a small spot by adsorption or drying, and then placed close to the moderator foil. An automatic apparatus has been set up for the entire process including the recovery of H218O. (author)
