Performance of an electron cyclotron resonance ion source designed for isotope ratio mass spectrometry.

We have designed, built, and tested an electron cyclotron resonance ion source suited to the needs of an experimental program examining new methods of isotope ratio mass spectrometry using multiply charged ions. Contaminant levels have been reduced to low levels. Sample absorption and desorption effects are under investigation and preliminary results are presented. © 2008, American Institute of Physic
