Modeling of mass spectrometers using linear and nonlinear ion mirrors

Abstract

The paper presents basic relations for calculating the parameters of mass spectrometers using ion mirrors with linear and nonlinear distribution of the axial potential. The results of simulations of the two types of spectrometers are presented as well as the results of calculating the dependence of the instrument’s resolution on the mass for various proportions of the field-free area length, the accelerating potential and the initial energy spread. Conclusions are made about the advantages of mass spectrometers using ion mirrors with nonlinear distribution of the axial potential on the basis of the data obtained.
