A0175001 11 (ISOCY,2GERJUL) Deuteron beam. A0175001 12 SAMPLE The target system consists of 4 single cylinders A0175001 13 filled with neon at normal pressure. They were arrangedA0175001 14 and adjusted similar to a stacked foil system. A0175001 15 The individual targets consist of a silver plated A0175001 16 brass cylinders of 20 mm inner diameter and 25 mm A0175001 17 length, sealed by 20 mm aluminium windows. Silver A0175001 18 coating was used to trap the fluorine as water-soluble A0175001 19 AgF on the wall surface. A0175001 20 In addition, the inner surface was coated with a thin A0175001 21 layer of NaF by evaporating an aqueous NaF solution. A0175001 22 Each target is equipped with two valves for rinsing A0175001 23 the 18-F from the wall after irradiation.
