Abstract
The elastic scattering in the tandem field mass analyzing systems is considered. The analysis includes deflecting electrostatic and magnetic converging, dispersing, diverging fields, and also the fields of quadrupoles. The influence of slits located on the ion beam path is indicated. An example illustrates the effect of slits on the elastically scattered current distribution in a double focusing mass spectrometer. Another example gives an idea about the influence of the diverging field on the peak tails in mass spectra.
