Application of rotating disk electrode technique for the preparation of Np, Pu and Am α-sources

Method of electrodeposition on rotating disk cathode (RDE) is applied for preparation of Np, Pu and Am α-standards. Phenomenon of critical current density is experimentally observed which is in perfect accord with Hansenʹs theory of electrodeposition. Influence of deposit calcination regime on quality of α-sources is studied, and comparison is made of uniformity of deposits obtained in various deposition systems. Standards with energy resolution better than 9 keV can be reproduceably obtained by optimized RDE electrodeposition technique.
