Abstract

Some methods of electron, ion and photoelectron spectroscopy deal with very weak, strictly oriented beams of charged particles. Because of low beams intensity, these methods are substantially non-destructive, but on the other hand, the beam weakness limits severely their sensitivity and rapidity of spectra registration. Electron-optical characteristics of electrostatic potential (Phi) equals arctg(y/x) are considered. Compared to `traditional' fields used in energy analysis and monochromatization of electron beams, the potential (Phi) possesses some extra compressing feature. This gives additional possibility to enhance the entrance flows to be analyzed or monochromized, and as a result can allow to improve sensitivity and rapidity of some modern electron and ion spectroscopic methods.
