Investigation of Magnetic Saturation In Central Iron Plate of Triplet Electron Lens

Abstract

In this research , the triplet projector magnetic electron lens under considerationconsists of three different geometrical shape lenses mounted back to back , wherethat the combination of the two back plates of this lens forms the central iron plate .The magnetization of the two central iron plates has been investigated at differentpoints with the aid of some computer programs.The significance of the present work lies in knowing the proper operating voltageto maintaining the favorable focal properties and reducing any magnetic fluxleakage.
