On the chromatic aberration of magnetic lenses with a field distribution in the form of an inverse power low (B(z) ∝ z –n )
Abstract:The chromatic aberration of magnetic lenses with the field distribution in the forms of inverse law have been studied by analytical and digital methods. These aberrations can be expressed in terms of Bessel function of fraction order. Analytical expressions for chromatic aberration coefficients of the spherical field model, which is useful for the study of single-pole magnetic lenses, are given.
