Preparation of the Elemental Form of Enriched Isotopic Materials for Target Fabrication

A review of reduction techniques employed to produce metal for the fabrication of isotopic targets used in nuclear physics is presented. The methods discussed take into account the small quantities of material available, as well as the chemical forms in which the separated isotopes are provided. For some materials, several alternative reduction techniques are given to allow for variations in available equipment and the final fabrication technique to be employed. Advantages and disadvantages with respect to yield and resultant metal purity are discussed. A table of pertinent data and recommendations is presented.
