Focusing Properties of Inhomogeneous Magnetic Sector Fields

“…The profile of the pole face is then a straight line, and hence the slope da/dp, evaluated from (14), must be constant. Thus the coefficients of the p 2 and p 3 terms must vanish, and we have…”

“…(14), needed to minimize second-order aberrations (see Table 2). With this modification the resolution would be increased to 910.…”

“…8 - 14 Theoretical calculations of the ion-optical properties of these magnetic lens systems in which both the source and collector ore located within the field boundaries have been treated by several authors.…”
