Abstract

Nickel targets for the cyclotron production of 64Cu were prepared by electrodeposition on a gold backing from nickel chloride solutions using boric acid as buffer. Parameters studied were nickel chloride and boric acid concentration, temperature and current density. All plating conditions studied were successful obtaining efficiencies of approximately 90% in 2–3h, reaching almost quantitative plating (>97%) in 10–20h depending on the current density. All plated targets withstood proton irradiations up to 40µA for 2h. Recovered nickel was successfully recycled and reused with an overall efficiency >95%.
