Influence of Saturation of Magnetic Lens Material on Fields of Deflectors and Parasitic Fields

Popis výsledku v původním jazyce

In the connection with the calculation of parasitic fields of highly saturated lens in emerged the problem of calculation of the field of deflectors situated next to saturated magnetic materials. Up to date the deflection fields were studied only near rotationally symmetric materials with constant permeability. However, for the deflectors in saturated magnetic lenses the relative permeability is very inhomogeneous and near pole piece tips it is close to 1. We have therefore modified the computation of deflection fields in saturated lenses with EOD program to include the real value of permeability of magnetic materials. We can also display the distribution of permeability in the magnetic circuit of the lens to understand the changes in the field distribution in deflection or parasitic fields and to understand the saturation effects in magnetic lenses.
