Spectrograph of charged particles consisting of a discrete plane electrode with different potential distributions and a grounded box-shaped electrode

Abstract

A simple two-electrode spectrograph that has been proposed by the author for fast analysis of the beams of charged particles with respect to energy is theoretically studied. A specific feature of such a spectrograph lies in the fact that the system makes it possible to apply different potentials to fragments of the split plane electrode. Computer simulation is used to determine the optimal working regimes of the spectrograph in which the range of simultaneously measured energies of the beams that are focused on one line increases with a decrease in the growth rate of potentials at the discrete plane electrode and amounts to a maximum known level of two orders of magnitude.
