Abstract

Ultra-sensitive detection by accelerator mass spectrometry of the long-lived plutonium isotopes, ^{239,240,242,244}Pu, has been demonstrated at an accelerating voltage of 300 kV. Transmission efficiencies as high as 15% have been observed for Th³⁺ ions. Using a gas ionisation detector with an ultra-thin silicon nitride window, an energy resolution sufficient to separate Pu³⁺ ions from interfering Dy²⁺ ions with 2/3 of the energy was possible. Sensitivities approaching 10 ⁶ atoms for the various Pu isotopes were achieved.
