Design of an Einzel Lens Using Non-Classical Variation Technique

   A computational investigation has been carried  out in  the  field  of  charged-particle  optics.  The work  is concerned with the design of einzel (uni potential)  lens by using non-classical variation method under different magnification conditions.The potential field distribution of the einzel lens has been represented by an analytical function. The paraxial ray equation has been solved for finding the short beam trajectory of the charged particles traversing the lens.
