An upgraded ion source for a mass spectrometer

Abstract

A model analysis of ion sources for dynamic mass spectrometers was performed, and the design of an upgraded ion source, which substantially reduces the ion energy spread, allows optimization of the zone of ion extraction from the source, and provides a high sensitivity of the instrument in the operation with low-energy ionizing electrons (down to threshold energies), was developed. Methodological techniques that allow one to analyze and calculate numerical model variants of ion sources of various designs using the SIMION 3D 7.0 program were developed.
