MASS SPECTROMETER INVESTIGATION OF ELECTRON IMPACT PROCESSES AT PRESSURES TO 1 MM HG

Abstract

A mass spectrometer for the study of secondary reactions involving ions, excited species and molecules is described. The instrument was checked with the Hornbeck-Molnar process for He2(+) formation in He, O3(+) and O4(+) formation in O2 and N3(+) and N4(+) formation in N2. Source pressures to about 1 mm Hg are used. The electron beam is controlled by the retarding potential difference technique for reducing the effective width in energy of the electron distribution.
