دراسة زيغ التشويه في العدسات المغناطيسية المزدوجة

Abstract

In this work, a computational theoretical investigation has been introduced to study the distortion aberration in magnetic lenses when it use as projector lens in transmission electron microscope. In this study the synthesis procedure method has been used by using the analytical mathematical function to represent axial magnetic field for doublet projector magnetic lens to obtaining the magnetic polepeices with rotation and distortion free.
