Improved composite targets for small scale 64Cu production comparing Au- and Pt-foils as 64Ni backing.

Advantages of a stacked assembly of target support components for ⁶⁴Cu production via ⁶⁴Ni(p,n)⁶⁴Cu reaction were reported recently. The present work shows the applicability of these composite targets for beam currents up to 22 μA. Gold and platinum foils were evaluated as ⁶⁴Ni backing. The effective specific activity (ESA) and specific activity (SA) were determined by TETA titration at room temperature and at 80 °C and compared with additional copper quantification results via ICP-MS and stripping voltammetric trace analysis (VA).
