Progress with a gas-accepting ion source for Accelerator Mass Spectrometry

[摘要] The National Ocean Sciences AMS (NOSAMS) facility at Woods Hole Oceanographic Institution has developed a novel, gas-accepting microwave-plasma ion-source. The source is a key component of a compact Accelerator Mass Spectrometry (AMS) system built for the analysis of (14)C in a continuously flowing gas stream. The gas source produces carbon currents from a stream of CO(2) with currents typical of a traditional graphite source. Details of the gas source, including ion current achieved, optimal flow rate, efficiency, and memory are presented. Additionally, data obtained from coupling a gas chromatograph to the source shown. Details about ion optics are presented separately [1]. Published by Elsevier B.V.
