Abstract

Any axially symmetric magnetic field produced by current-carrying coils with or without ferromagnetic materials or by permanent magnets is a magnetic lens (see Sections 4-4 and 4-7). As we know, the distinctive feature of magnetic lenses is that their optical properties are dependent on the charge-to-mass ratio of the particles. Stationary magnetic fields cannot accelerate charged particles; therefore in t he absence of electrostatic fields magnetic lenses leave their energy unaltered.
