Abstract
An improved electron current and energy regulator for mass spectrometer ion sources is described. The improvements over previous regulator circuits consist of (a) a two kilocycle filament excitation supply which allows improved filament emission control and (b) a method of controlling the filament to shield voltage over a wide range of electron energies. Data on isotope ratio measurements are provided to show the increased stability over that of previous regulators.
