Actinide Target Preparation at IRMM - Then and Now

Since the beginning of its activity, IRMM (originally CBNM) was engaged in measurements of parameters relevant to the nuclear energy. High purity samples and targets of radioactive materials required for measurements of cross-sections and studies of fission fragments or fuel elements were prepared by IRMM's target group by means of various techniques reviewed in this presentation. Applying these techniques, the target group has been preparing targets of U, Pu, Np, Am, Th for in-house physicists and for external customers. Recently, after a process of decontamination and refurbishment of the old equipment, targets made of some U isotopes have been prepared by electrodeposition and high-vacuum evaporation. Other actinide targets (Hf, U, Th) have been prepared using mechanical reshaping techniques.
