New approach for consideration of action of charged particle magnetic spectrometers

A new approach to the consideration of corpuscular-optical action of the magnetic spectrometer is proposed. A method of producing a unique and simplified representation of the coefficients of the transformation of the charged particle beam produced by dipole and quadrupole magnets is proposed. Main characteristics of the magnetic spectrometer resolution and acceptance are analysed on the basis of such parameters as relative area of the radial cross section of the particle beam in the magnetic field of the spectrometer and relative dispersion which express in the simplest way its limit possibilities
