Abstract

1414907 Ion sources for mass spectrometry AGENCE NATIONALE DE VALORISATION DE LA RECHERCHE 10 Dec 1973 [22 Dec 1972] 57024/73 Heading H1D A method of chemical analysis comprises placing a substance 19 in a conductive box 16 at a constant potential and bombarding the substance with a beam 6 of molecules, e.g. of a rare gas, to cause sputtering of the substance with the release of ions which are extracted to a mass spectrometer 13, 14, 15 for analysis. To generate the molecular beam an ion source 1 produces a beam of ions which is focused on a charge-exchange device 4 producing ions which are deflected as shown at F, whereas the molecules pass on to bombard the sample. An A.C. voltage applied to plates 3 results in a pulsed molecular beam. The molecular beam energy can be between 6 and 20 keV.
