โœฆ Synopsis

A tandem target for the simultaneous production of [ 18 F]-fluoride and [ 11 C]CH 4 with 18 MeV protons has been manufactured and evaluated. Tungsten was chosen as a grid material because of its good mechanical and thermal properties. Four tungsten grids were placed between the liquid target cavities and between the air cooling units. This tandem target system showed a stable production yield and thus appears to be suitable for a routine production of [ 18 F]-fluoride and [ 11 C]CH 4 with 18 MeV protons.

A simple double liquid chamber target was developed to provide the option for simultaneous production of [15O]H2O and either 13N or 18F using a single proton beam. Irradiation of natural water in a thin aluminium front chamber produced [15O]H2O by the 16O(p, pn)15O reaction directly. Large (0.5-1.0
