M. Swank, C. M. O'Shaughnessy, M. Paul, and L. Yang Many important experiments such as the neutron electric dipole moment and lifetime, or properties of superfluid helium require superpure helium, i.e., helium with a million times smaller 3 He contamination compared to natural helium. Whereas, in principle, techniques are available to produce superpure helium, no experimental techniques have been available to measure such a small concentration. This paper details the use of accelerator mass spectrometry (AMS) to measure the 3 He concentrations in superpure helium. [Phys. Rev. C 93, 065502] Published Mon Jun 13, 2016
