Mass spectrometer based on conversion of spectra

This article presents the results of numerical investigations of mass analy zer parameters. The principle of mass spectrometer operation is based on th e shock mechanism of the ion beam conversion of spectra. Mathematical simul ation of the ion motion is carried out in the fields of a mass spectrometer consisting of an ion source converter and an energy analyzer with a two-di mensional electrostatic field and a plane of symmetry. A mass spectrometer of this kind is shown to have the following parameters: 1-1600 u-operationa l mass range, similar to 1600 mm-relative mass resolving power, similar to 300 mm-the maximum dimension of the mass analyzer. We have established the basic requirements to be met by the electric pulse generator that will prov ide the operation of the mass spectrometer under study.
