A gas-accepting ion source for Accelerator Mass Spectrometry: Progress and Applications
The National Ocean Sciences Accelerator Mass Spectrometry (NOSAMS) facility at the Woods Hole Oceanographic Institution has developed an Accelerator Mass Spectrometry (AMS) system designed specifically for the analysis of C in a continuously flowing stream of carrier gas. A key part of the system is a gas-accepting microwave ion source. Recently, substantial progress has been made in the develo...
متن کاملABSTRACT Title of Dissertation: A GAS-INJECTION NEGATIVE ION SOURCE FOR ACCELERATOR MASS SPECTROMETRY
Title of Dissertation: A GAS-INJECTION NEGATIVE ION SOURCE FOR ACCELERATOR MASS SPECTROMETRY Scott Joseph Tumey, Doctor of Philosophy, 2004 Dissertation directed by: Professor Alice C. Mignerey Department of Chemistry & Biochemistry Accelerator mass spectrometry is an ultra-sensitive isotopic analysis technique that allows for the determination of rare long-lived radionuclides such as radiocarb...
متن کاملOptimizing a microwave gas ion source for continuous-flow accelerator mass spectrometry.
A 2.45 GHz microwave ion source coupled with a magnesium charge exchange canal (C × C) has been successfully adapted to a large acceptance radiocarbon accelerator mass spectrometry system at the National Ocean Sciences Accelerator Mass Spectrometry (AMS) Facility, Woods Hole Oceanographic Institution. CO(2) samples from various preparation sources are injected into the source through a glass ca...
متن کاملNew Cs sputter ion source with polyatomic ion beams for secondary ion mass spectrometry applications.
A simple design for a cesium sputter ion source compatible with vacuum and ion-optical systems as well as with electronics of the commercially available Cameca IMS-4f instrument is reported. This ion source has been tested with the cluster primary ions of Si(n)(-) and Cu(n)(-). Our experiments with surface characterization and depth profiling conducted to date demonstrate improvements of the an...
متن کاملUse of an Ecr Ion Source for Mass Spectrometry
At ANSTO we have developed an Electron Cyclotron Resonance (ECR) ion source to investigate new concepts for mass spectrometers designed to measure isotopic ratios of elements such as carbon, nitrogen and oxygen. The low pressure ECR plasma presents particular challenges when used for mass spectrometry. The elements we are interested in measuring are typically present as residual gas in vacuum s...
