| Summary: | Several innovative designs were designed for magnetic lenses, a bipolar lens with innovative and different geometric shapes, where the outer Inner pole side of the iron shroud, which is symbolized by the symbol (L), was changed. 2,4,6 A/mm2) and after it was designed, the engineering parameters were studied in terms of magnetic properties, i.e., calculating the magnetic flux density with different current densities, and then studying the optical properties in terms of spherical aberration as well as chromatic aberration. Which made slight changes to the magnetic and optical properties of the bipolar lens and led to an improvement in the performance of the lens because the resolving power increased its amount when the change was made, as well as the aberration where both spherical aberration and chromatic aberration decreased. |
