Production, Collection, and Purification of ⁴⁷Ca for the Generation of ⁴⁷Sc through Isotope Harvesting at the National Superconducting Cyclotron Laboratory.

ABSTRACT: An experiment was performed at the National Superconducting Cyclotron Laboratory using a 140 MeV/nucleon ⁴⁸Ca beam and a flowing-water target to produce ⁴⁷Ca for the first time with this production route. A production rate of 0.020 ± 0.004 ⁴⁷Ca nuclei per incoming beam particle was measured. An isotope harvesting system attached to the target was used to collect radioactive cationic products, including ⁴⁷Ca, from the water on a cation-exchange resin. The ⁴⁷Ca collected was purified using three separation methods optimized for this work: (1) DGA extraction chromatography resin with HNO₃ and HCl, (2) AG MP-50 cation-exchange resin with an increasing concentration gradient of HCl, and (3) AG MP-50 cation-exchange resin with a m
