The study concern with using local Kaolin of Duekhla to prepare Anorthite material. The sequence of study started with washing, chemical treatment and sedimentation to produce a fine powder by passing the product through a special sieve (less than 20 µm).then after this step dividing the fine powder product into two groups, the first group with out heat treatment and the second with heat treatment (calcinations) at 400 oC.
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.
In this work, a program of ray tracing program has been constructed. Thisprogram includes ray tracing for:
1. Skew ray tracing for spherical surfaces;
2. Skew ray tracing for Cartesian or quadric surfaces of revolution (conic surfaces).
