Abstract

A model of a new type of a monochromator for the ion beam emitted by mass-spectrometric ion sources with a broad energy distribution is considered. The ion beam monochromation was carried out by transforming the energy spectrum of particles in high vacuum by the shock effect produced by electric pulses on ions in a spatially nonuniform field followed by the formation of an ion beam in the electrostatic field of the immersion lens. Numerical simulation of the operation of the monochromator proves its performability as a compact and effective instrument for solving the problem of monochromation in mass-spectrometry.
