A tandem target for the simultaneous production of [F-18]-fluoride and [C-11]CH4 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 [F-18]-fluoride and [C-11]CH4 with 18 MeV protons.
