أمثلة العدسات المغناطيسية المزدوجة عديمة الدوران و التشويه باستخدام الأنموذج الكاوسي

Abstract EN

In the present work, a computational simulation has been introduced to describe one of the optimization methods of electron lenses.

This study concentrates to find optimum design of polepieces of free rotation and distortion doublet magnetic lenses by using one of magnetic field models that which known in electron optics (Gaussian Model), as target function for the axial magnetic field.
