| dc.abstract.en | A methodology for electrochemical preparation of nickel layers intended to be used as targets for charged particle accelerators is proposed. The goal is to deposit the majority of metal dissolved in the electrolytic bath during a reasonable time (no longer than several hours) providing an acceptable quality of the deposits in terms of purity, surface roughness, compact and crack-free structure and mechanical stability. The electrodeposition is carried out from novel aqueous baths prepared by dissolution of a metal powder in a HNO 3 -free solution due to the limited availability of isotopically enriched nickel concentration of the metal in the bath is low or moderate. This factor combined with the requirement of deposition of all dissolved metal makes serious differences between the target deposition and regular industrial plating. The impact of the electrolytic bath pH and the plating current density is analysed in order to optimise deposition parameters. The pH was varied from 3.8 to 5.3 while the applied current density ranged from 30 to 240 mA cm −2 . Progress in the deposition process was analysed using in situ UV–vis spectroscopy while a scanning electron microscope was applied to study the morphology of the deposits. Optimal electroplating conditions, which allow relatively fast deposition (up to ca. 7.2 h) of good quality metallic deposits containing most of the metal present in the bath (≥ 95%), are suggested. |
