Abstract

Experiments are underway at Argonne National Laboratory to measure the ⁴¹Ca radioisotope concentration (T_{1 2} = 100 000 years) in natural samples of terrestrial origin by accelerator mass spectrometry (AMS) [1]. Since the concentration of ⁴¹Ca in these samples is expected to be very low, enrichment with a Calutron Isotope Separator at Oak Ridge National Laboratory is being used. This separator requires rather large quantities of high-purity Ca metal (typically 100 g/loading) as source material. Details of the methods of obtaining these metallic samples from various materials will be presented.
