Development of Accelerator Mass Spectroscopy Techniques for Measuring $^3$He-$^4$He Isotopic Ratios

Abstract

A variety of research efforts require isotopically purified helium with a ratio of $^3$He to $^4$He at levels below that which can be measured using traditional mass spectroscopy techniques. We have developed an approach using accelerator mass spectroscopy that is shown to reach the $10^{-14}$ level of sensitivity, several orders of magnitude more sensitive than other techniques. We argue that there is a clear path forward to improvement of at least another order of magnitude.
