Abstract

A procedure for calculating the potential and field of multipole lenses in which the central part of the poles has the form of an ideal curve is presented. The procedure is based on the method of conformal mapping. The properties of these lenses are compared with those whose poles have a polygonal profile. It is shown that sufficiently wide ideal-center poles provide a better field quality than polygonal poles.
