Abstract

Electrodeposition is a relatively simple and high yielding method for producing actinide layers for nuclear targets. A new design of cell has been used to deposit uranium (U), plutonium (Pu), neptunium (Np) and americium (Am) onto metallic backings from isopropanol and onto carbon coated polyimide films from isobutanol. The current density was 1 to 3 mA.cm{-2}. Deposition yields, determined by low geometry alpha particle counting, were about 65% for Pu and about 90% for the other elements. The same technique was used to investigate thickness homogeneity of (239)Pu deposits and it was observed that targets with mean thickness up to about 100 µg.cm{-2} were thicker in the centre that at the edge, but for targets about 100 µg.cm{-2} this profile was reversed. Modifications to the electrode shape were made in an attempt to improve the thickness uniformity.
