Gas mass spectrometer with a non-linear ion mirror

This article provides a brief description of existing TOF ion focusing methods in mass spectrometers, we compare the mass spectrometer using ion mirrors with linear and nonlinear distribution of axial potential. Researchers have considered the basic equations for the calculation of the ion-optical systems, the results of simulations of two types of spectrometers, the results of calculations depending on the resolution of the instruments of mass and initial energy spread of ions. We derive the advantages of mass spectrometers with nonlinear distribution of axial potential ion mirrors based on these obtained data.
